The Secure Sockets Layer (SSL) protocol is essential for keeping communications on the Internet secure. It encrypts data sent between web browsers and websites, ensuring the privacy and integrity of information exchanged.

However, sometimes you may run into problems where you cannot make an SSL connection. In this article, you will learn more about common causes and solutions to this problem.
Connection without SSL: possible causes
1. Expired SSL certificate
A common reason for connection problems with SSL is an expired certificate on the website. If the certificate is not up-to-date, the browser will not trust the connection.
2. Misconfigured SSL certificate
Errors in the configuration of the SSL certificate, such as a wrong name or missing essential components, can also cause connection problems.
3. Weak or outdated encryption
Browsers refuse to connect to servers that use outdated or encryption methods considered insecure.
4. Firewall or antivirus settings
Sometimes firewall or antivirus programmes can block or disrupt SSL connections, especially if they are configured incorrectly.
5. Difference in time between server and browser
Significant differences between browser and server system time can lead to SSL errors.
No connection via SSL: how to solve it
Step 1: check the validity of the SSL certificate
Use online tools such as SSL Labs’ SSL Server Test to check if the SSL certificate is valid and correctly configured on the server.
Step 2: update browser and operating system
Make sure your browser and operating system are up-to-date, as older versions may not support modern SSL protocols.
Step 3: update firewall and antivirus settings
Check that your firewall or antivirus is not the cause of the problem by temporarily disabling them. If this solves the problem, add an exception for SSL connections.
Step 4: Configure SSL settings
In some cases, you may need to adjust the SSL settings on your device. This may invo
