Nextcloud version : 23.0.2
Operating system and version : docker instance
Apache or nginx version : nginx on nextcloud docker + nginx with letsencrypt for reverse proxy
PHP version : 7.4
Context :
- I successfully migrated from version 21 to 23, system was up and running fine
- I decided to migrate the db from mariadb to pgsql (running both in a separate docker instance). Migration appeared to work fine
- I manually updated my conf.php in order to change db hostname/user/password
Error :
Unfortunately I am now having a login loop even if I put in the right credentials.
It tries to connect and looks like it is working but after ~30 seconds it gets back to the login page.
I have tried to login several times and now nextcloud thinks I am trying to bruteforce 
Do you guys have any idea what I should look at to get it back working ?
Here is my config.php :
<?php
$CONFIG = array (
'memcache.local' => '\\OC\\Memcache\\APCu',

0 => 'letsencrypt',
),

I checked the error.log on var/lib/nginx/logs for both my nextcloud docker and reverse proxy and it’s empty.
Any help on my problem would be appreciated
