What happened?

• The config file and certificate work fine for PHP 8.1.
• But as soon as PHP 8.2 or 8.3 are implemented the following error is thrown

[PDOException]
PDO::__construct(): Unable to set local cert chain file `/run/secrets/mysql
/tls.crt'; Check that your cafile/capath settings include details of your certificate and its issuer
See more below.

What should happen?
SSL cert should be found when connecting to db with PHP 8.2.

How can this be reproduced?
To reproduce the problem:

Update to either PHP to 8.2 or 8.3*
Matomo will fail to connect to the database; it breaks Matomo**
Roll back to PHP 8.1***
Matomo works normally
*PHP 8.2-fpm-alpine or PHP 8.3.8-fpm-alpine
**The error is [PDOException]
PDO::__construct(): Unable to set local cert chain file `/run/secrets/mysql /tls.crt'; Check that your cafile/capath settings include details of your certificate and its issuer
But the config file is fine when using PHP 8.1.
