I cannot connect via SSL

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

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
