This server is not exposed to Internet so I can't give access to it. I made the test with Firefox, Chrome or Edge with no success.
I'm installed a new server and it seems to be working. My guess is that the Debian upgrade from 10 to 11 made a mess months ago but I didn't saw it because I didn't need to install/upgrade anything since (until yesterday when I updated aapanel after having php8.1 installation problem).
I will backup/restore sites from the old server to the new and that's going to be OK. Not ideal but it's quick and easy!
Thank's for the support anyway, I really appreciate 🙂
