Can't access backend. Error SQLSTATE[HY000] [2026] TLS/SSL error: invalid directory

Hi! First off I did no changes since the last time I tried to log in, I suddenly came up to an error 500 when trying to log into the back office.

The error log from /vendor shows:

PHP Fatal error:  Uncaught PDOException: SQLSTATE[HY000] [2026] TLS/SSL error: invalid directory in /home/name/public_html/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:27

The line 27 in pdoconnection.php is   parent::__construct($dsn, $user, $password, $options);

Hosting support told me to try and change the php versions. I tried everything from 7.0 to 8.4 and didn't make any difference (except when i selected 7.0, then the front office also stopped working), apart from that they can't help me. Current one is 7.4

I'm not a developer so I'm pretty lost trying to fix this. Any ideas?

Thanks in advance

Solved! Posting the fix in case it can help somebody in a similar situation.

There was an update of MariaDB on the servers, and this issue might have been related to it. Using the debug mode on the backend page it threw an 500 error related to the blockwishlist module. Hosting support fixed it. After that the dashboard was accesible but the 500 error kept popping up in the order panel, related to the paypal module. That got fixed when i uninstalled it. I assume it will get fixed when I get the updated version to reinstall. After that I cleared the prestashop caché using the terminal in cpanel.

In any case, the error was related to some updates on the server and some modules broke and crashed the dashboard and other pages on the backend.
