PHP-FPM Session handler is via redis5 cluster.
Nodes are behind AWS ALB. Log in works fine and once logged in everything works okay.
But when you log out you get an internal server error from Nextcloud:

Is this the first time you’ve seen this error? Y:
Yes since shared session cache is configured in php-fpm
Steps to replicate it:
- Log in.
- log out
- Log in for the same user will be denied at the next attempt until redis cache is flushed
