You are trying to open your favorite website or enter an application, but instead of content you see a scary message ERR_SSL_PROTOCOL_ERROR or the message “SSL connection error 107”. This phenomenon is not uncommon for mobile device users, and it completely blocks access to protected resources on the Internet. The SSL (Secure Sockets Layer) protocol is responsible for encrypting data between your phone and the server, ensuring the security of the transfer of personal information.
When the browser or system Android cannot establish a secure connection, they interrupt the page loading to protect you from potential threats. However, often the reason lies not in hacking, but in a simple failure of date settings or outdated software. In this article, we will analyze in detail the technical causes of this problem and offer step-by-step methods for eliminating it, from simple reboots to complex manipulations with certificates.
You should not ignore this failure, as it may indicate that your browser does not trust the site, or that the device itself has lost synchronization with world time. Understanding the nature of the error will help you quickly regain access to the network without losing important data or the need to reset the phone to factory settings.
The nature of the SSL error on mobile devices
Error code 107 in the context of security protocols usually indicates that the handshake between the client (your smartphone) and the server (the site you are visiting) failed. This occurs due to mismatched encryption protocol versions or problems with the digital certificate. The server may require a more modern version TLSwhile your browser is configured to use outdated standards.
Often the culprit is the site's digital certificate itself. If it has expired, been revoked by a certificate authority, or was issued by an untrusted authority, the security system of Chrome or another browser instantly blocks the connection. This is a security mechanism that prevents passwords and card details from being shared with scammers.
⚠️ Attention: If the error appears only on one specific site, and other resources are working fine, the problem is most likely on the side of the owner of this site, and not in your phone.
In some cases, anti-virus software or firewalls installed on the device can intercept traffic and replace scanning certificates, which causes a trust conflict in the browser. It is also worth considering that some corporate networks use their own certificate authorities, which are not recognized by the mobile operating system by default.
Technical details of the protocol
SSL and TLS are cryptographic protocols that ensure communication security. Error 107 often occurs when the client and server cannot agree on a common cipher suite to establish a connection.
Checking the system date and time: the first step to a solution
The most common, but most common reason for an SSL connection failure is an incorrectly set date and time on your device. Digital certificates have a strict validity period, and if your phone's clock is slow or fast even by a few days, the browser will consider the certificate invalid.
To fix this, you need to go to the system settings. Find the section System → Date and time (the path may vary slightly depending on the model Samsung, Xiaomi or Pixel). Make sure that the "Use network time" or "Automatic time adjustment" switch is activated.
- 🕒 If automatic adjustment is enabled, but the time is incorrect, try turning it off, setting the correct values manually, and then turning it on again.
- 🌍 Check your time zone: it should match your current location, and not the place where you bought the phone.
- 🔄 After changing the settings, be sure to restart the browser so that it requests the latest data from the server again.
Sometimes a complete reset of the time settings helps. Turn off automatic sync, set the date back a year, save, and then return to automatic. This action forces the system to forcibly request the current time from the cellular operator or Wi-Fi router.
If you have a dual-SIM phone, try switching the mobile data to another SIM card. Different operators may transmit time data with different accuracy or latency.
Clearing cache and browser data
Accumulated temporary browser files may contain outdated or corrupt certificate data, resulting in persistent errors when trying to load a page. Clearing cache and cookies is an effective way to eliminate software conflicts without deleting your browsing history (if you select the option correctly).
To perform this procedure, go to the settings of the browser application you are using (for example, Google Chrome). Find item Privacy and security → Clear history. It is important to select the correct time range here - it is best to specify "All time" to ensure that problematic files are deleted.
Settings → Applications → Chrome → Storage → Clear cacheNote the difference between clearing cache and clearing data. Resetting your data will delete all your saved passwords, bookmarks (if not synchronized) and browser settings, returning it to its "as-installed" state. Use this method if simply clearing the cache does not help.

Resetting network settings on Android
If the problem is more global in nature and affects not only one browser, but all applications that use the Internet, the network settings of the operating system may be damaged. Resetting network settings will return Wi-Fi, mobile data and Bluetooth settings to factory settings.
This procedure is safe for your personal files, photos and contacts. However, you will have to re-enter the passwords for all Wi-Fi networks you previously connected to and re-pair your Bluetooth headsets. Go to menu System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.
| Action | What is saved | What is deleted |
|---|---|---|
| Reset network | Photos, contacts, applications | Wi-Fi passwords, Bluetooth settings |
| Reset applications | Files, media | Settings of all installed apps |
| Full reset (Hard Reset) | Nothing | All user data |
After the reset, the phone will automatically reboot. Wait until the system boots completely and try connecting to the network again. This often solves problems with routing and incorrect DNS queries that can mimic SSL errors.
Resetting network settings is the "middle ground" between simply rebooting and completely resetting the phone, often resolving complex connection problems.
Updating WebView and browser components
B ecosystem Android a critical component for displaying web pages is Android System WebView. It is a system service that allows other applications to display web content. If its version is outdated, it may not support the new encryption standards required by modern sites.
Go to the application store Google Play Market and enter "Android System WebView" in the search. If the Update button is available, be sure to follow this action. A similar procedure should be carried out for your main browser, be it Chrome, Firefox or Samsung Internet.
Sometimes the update is not available due to regional restrictions or OS version. In this case, you can try to remove updates to the WebView component (through application settings) so that the system rolls it back to the factory version, and then check for updates again.
The influence of antiviruses and third-party software
Third-party security applications, VPN services, and even some traffic-saving apps can interfere with the SSL connection setup process. They use a "Man-in-the-Middle" technique to scan traffic, exposing their certificates, which the browser does not recognize as trusted.
Try temporarily disabling your antivirus or firewall. If the error disappears, then the problem is in the settings of a specific application. You will need to add the site to exceptions or update the antivirus signature database. It is also worth checking whether you have activated the “Traffic Saving” mode in your browser, which passes data through its servers.
⚠️ Attention: Disable security software only for the duration of the diagnosis and only on sites you have checked. Do not disable your antivirus when visiting suspicious resources or logging into banking applications.
If you use a corporate profile on your phone or special certificates for work, make sure they have not expired. In the security settings in the "Encryption and Credentials" section, you can view the list of installed user certificates and remove those that are in doubt.
Why does a VPN cause an error?
Many free VPNs use outdated encryption protocols or overloaded servers that cannot correctly process the certificate request, breaking the connection.
What to do if all else fails
In rare cases, SSL error 107 may indicate deeper problems in the device firmware or hardware malfunctions of the network module. If all of the above methods do not work, you should consider resetting your phone to factory settings.
Before this step, be sure to back up all important data in the cloud or on your computer. A reset will delete all information from the internal memory, but may eliminate software conflicts that have accumulated during use of the device.
If, even after a full reset, the problem persists on all sites and in all applications, this may indicate that the device needs to be reflashed at a service center or a physical breakdown of the communication component. In such a situation, self-repair may lead to a complete loss of warranty.
Why does the error only occur in Wi-Fi, but not on the mobile data?
This indicates a problem with your router or provider. Perhaps the router has outdated software installed, the date is incorrect, or the provider blocks certain encryption protocols. Try rebooting the router or updating its firmware.
Is it possible to ignore the error and go to the site?
Some browsers have a button "Advanced" -> "Go to the site (unsafe)". You can only do this if you are 100% confident in the security of the resource and do not plan to enter passwords or card data there. Ignoring an SSL error exposes your data to the risk of interception.
Does Android version affect the error?
Yes, older versions of Android (below 7.0) may not support modern TLS 1.3 encryption standards, which many sites require. In this case, the only solution is to update the operating system or replace the device with a more modern one.
How to check a site’s certificate manually?
On your computer, you can click the lock icon in your browser's address bar to view the certificate details. This is more difficult to do on a mobile device, but you can use online SSL checking services by entering the address of the problematic site.
