The sudden appearance of a message err connection refused on the screen of your smartphone can be an unpleasant surprise, especially when you urgently need to find information or send a message. This error means that the device cannot establish a connection to the target server, although the Internet connection itself may formally be present. Users often confuse this failure with a complete lack of network, but the nature of the problem lies deeper, in the plane of network settings or blocking at the routing level.
The situation when Android refuses to load pages or connect to applications can be caused by many factors: from failures in the Internet provider to incorrectly set DNS parameters. It is important not to panic and not rush to completely reset the device to factory settings. In most cases, the problem can be solved by sequentially checking several key network configuration parameters and clearing the system services cache.
This guide will help you independently diagnose the cause of the problem and fix it without contacting a service center. We will analyze both software solutions and specific settings that are often ignored by ordinary users. If you encounter that the browser Chrome or other clients refuse to connect, follow the steps described below to restore the functionality of your gadget.
Diagnostics of connection type and network status
First of all, you need to make sure that the problem is not global. Often err connection refused occurs due to temporary failures with the telecom operator or problems with the router to which the smartphone is connected. Try switching from Wi-Fi to mobile data or vice versa. If the error disappears when you change the connection type, then the problem is localized to a specific network interface or equipment.
Check whether other applications that require network access are running. If instant messengers function normally, but browsers display an error, the issue may be with proxy settings or ad blockers. If the Internet does not work anywhere, you will need a deeper check of the settings Access points (APN) or rebooting the network equipment.
⚠️ Attention: If the error appears only in one specific application, the problem may be on the server side of this service. Check the developer's official sources before changing your phone settings.
You should also pay attention to the date and time on the device. Incorrect system clocks can lead to SSL certificate errors, which are often disguised as connection refusals. Make sure that in the Settings → System → Date and time section, synchronization with the network is activated. This is a simple but critical step to establish a secure connection.
Clearing the DNS cache and browser data
The accumulated data in the DNS cache may contain outdated or incorrect server addresses, which directly leads to the appearance of the message connection refused. The system tries to contact an old IP address that no longer serves the requested domain. To solve this problem, you need to clear the DNS cache and the data of the browser itself that you use for surfing.
In modern versions Android there is no direct button for clearing the DNS cache, like on computers, but you can use airplane mode or reboot. A more radical but effective method is to clear browser application data. Go to Settings → Applications, find your browser (for example, Chrome or Firefox) and select “Storage”. There you need to click “Clear cache” and, if this does not help, “Clear data”.
- 🔄 Reboot the device in airplane mode: turn on airplane mode for 10 seconds, then turn it off.
- 🗑️ Clear the cache browser through application settings, without deleting your browsing history, if it is important.
- 🌐 Try opening the site in incognito mode to exclude the influence of extensions.
- 📱 Uninstall and reinstall the browser if the problem persists only in it.
Use incognito mode for a quick check: if the site opens there, This means the problem is in the extensions or the cache of the main browser profile.
After completing these steps, try opening the problematic site again. If the error err connection refused disappeared, then the reason lay in the local data of the device. Otherwise, you need to move on to more complex network settings, such as changing DNS servers.
Setting up private DNS and name servers
One of the most common reasons for connection failure is problems with your ISP's DNS servers. Switching to public and trusted servers such as Google DNS or Cloudflare will often resolve the issue instantly. In Android 9 and newer, this function is placed in a separate menu, which makes the setup simple and accessible to any user.
To change the settings, go to the section Settings → Connections → Advanced settings → Private DNS (the path may vary slightly depending on the model Samsung, Xiaomi or Pixel). Select the "DNS Provider Hostname" mode and enter the address of a trusted server. This action will encrypt your DNS requests and route them past potentially unstable operator servers.
| DNS Provider | Input host (Private DNS) | Features |
|---|---|---|
dns.google |
High speed and stability | |
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com |
Emphasis on privacy and security |
| AdGuard | dns.adguard.com |
Ad blocking at the DNS level |
| Quad9 | dns.quad9.net |
Blocking malicious domains |
After entering the address, click "Save." The device may lose connection for a few seconds, after which the network should be restored with new parameters. If, after entering the address, the error “Failed to connect” appears, check that the host is spelled correctly. Extra spaces or typos in the domain name will lead to a complete lack of Internet.
☑️ Checking DNS settings
Checking proxy servers and VPN connections
An active VPN connection or an incorrectly configured proxy server are classic culprits of the error err connection refused. If the VPN tunnel breaks or the proxy server is unavailable, traffic is blocked and the browser reports a connection refusal. You need to check the list of active VPN connections in the network settings.
Go to Settings → Connections → VPN. If there are active profiles there, try disabling them. It's also worth checking the proxy settings for your Wi-Fi network. Tap and hold your network name in the Wi-Fi list, select Change Network, and expand advanced settings. Make sure that the "Proxy" field is set to "No".
⚠️ Attention: Some corporate networks or educational institutions require the use of a proxy. Disabling these settings in such an environment will result in loss of access to local resources.
If you are using third-party applications to bypass blocks, make sure they are updated to the latest version. Outdated protocols may be blocked by the provider, which also causes a connection error. Try changing the server inside the application or the connection protocol, if such an option is provided by the developer.
Resetting the network settings on the device
If the previous methods did not help, it is possible that critical errors have accumulated in the system network configuration files. Resetting your network settings will return all Wi-Fi, Bluetooth, and mobile data settings to factory defaults. This is a safe procedure that does not delete your personal files, photos or installed applications.
To perform a reset, find the item in the menu Settings → System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings. On devices Samsung this item is often located in the General settings → Reset → Reset network settingssection. After confirming the action, the phone will reboot and you will have to re-enter the passwords for your Wi-Fi networks.
What exactly what is reset during this operation?
All saved Wi-Fi networks and passwords for them, paired Bluetooth devices, mobile hotspot settings and network selection preferences are reset. Personal data (contacts, photos, applications) remain untouched.
This step is especially effective when the error occurs after updating the operating system Android. New software versions may conflict with old network profiles, and a full reset allows the system to create a configuration from scratch, taking into account the current requirements of security protocols.
The influence of antiviruses and firewalls
Security applications installed on a smartphone can mistakenly block legitimate traffic, mistaking it for a threat. Antiviruses with the “Web Protection” or “Firewall” function often cause the appearance err connection refused on specific sites or in all applications at once.
Try to temporarily disable protection in your antivirus application or completely remove it during testing. If after this the Internet begins to work stably, then the problem is in the traffic filtering settings. Check the antivirus event logs to understand which connections are being blocked and add the necessary resources to the white list.
- 🛡️ Disable the “Protection on public Wi-Fi networks” function in the antivirus settings.
- 🚫 Check if the “Parental Controls” mode is enabled, which may block access.
- 📵 Uninstall applications to clear memory if they have network management functions.
Built-in defender Google Play Protect can also affect the operation of applications downloaded from other than the official store. If you use modified versions of apps, the system may block their access to the network for security reasons. In this case, the solution to the problem lies in the selection of software sources.
If the error disappears after removing the antivirus, configure exceptions in its filtering rules, rather than leaving the phone unprotected.
When the problem is on the side of the provider or server
Sometimes all manipulations with the phone turn out to be useless, because the source of the problem is located outside of your device. Your ISP may be blocking access to certain resources, or the server you are accessing may be overloaded or down. In such cases, an error err connection refused is a normal reaction to the inability to establish contact.
You can check the availability of a resource using third-party monitoring services or simply by trying to open the site from another device connected to a different network (for example, from a computer via a friend’s mobile data). If the site does not open anywhere, then it really is not available globally or in your region.
⚠️ Attention: Telecom operators periodically carry out technical work, which can lead to temporary connection interruptions. Typically, such work takes from 15 minutes to several hours.
It is also worth considering that some resources may be blocked at the request of regulatory authorities. In this case, standard configuration methods will not help, and you will need to use specialized tools to change the traffic route, if this is permitted by the laws of your country.
FAQ: Frequently asked questions
Why does the err connection refused error appear only in Wi-Fi, but the mobile data works?
This indicates a problem with your router or the settings of a specific router Wi-Fi networks. The router may be frozen, running out of connections, or have incorrect DNS settings. Try rebooting the router or forgetting the network on your phone and connecting again.
Can the error occur due to the phone's memory being full?
Extremely rare. Memory itself does not affect network packets. However, if the system does not have enough RAM to run network services, they may crash. Clearing the background and rebooting usually solve this problem.
What to do if resetting the network settings did not help?
If resetting did not help, the problem may be hardware (Wi-Fi module malfunction) or deep software (firmware conflict). In this case, it is recommended to perform a full reset to factory settings with a preliminary data backup or contact a service center.
Does the date and time affect the appearance of this error?
Yes, it does critically. If the time on the device deviates greatly from the real time, the sites' security certificates are considered invalid, and the connection is blocked even before the data transfer begins, which may look like a connection failure.
How to check whether the provider is blocking a specific site?
Try to open the site through the mobile data of another operator or use online services for checking site availability (for example, 2ip.ru). If the site is accessible through other networks, it means that your current provider is blocking access to it.
