thank you for your response.
Yes, the $paramDbPassword parameter is strictly identical on my two machines.
In summary, I have three servers:
1) The old one (let's call it S1), which worked until PHP 7.4.
- arch linux
- apache
- php 7.4
- mariaDB
2) The new (S2)
- ubuntu
- apache
- PHP 7.2
I set up S2 to connect to the database located on S1 but also on S3 (to test more freely).
3) I also have a maria DB server (S3) containing a copy (export/import) of the database located on S1. in order to safely test configuration modifications.
result (log level 4 on S2, attempt to connect to S3 from S2 - the result is the same if I try to connect from 2 on S1) :

I made a new test on S3. i reset the admion password with the update i found here
www.projeqtor.org/fr/forum-fr/5-ask-ques...t-password-for-admin
after that, i could login, and projeqtor asked me to change the password.
Then i can see some contents. I disconnected the session and tried to reconnect... no sucess, same error as before...
i think there there is something wrong with apache/php on my S2...
