Nextcloud Login Problem (Internal Server Error) after Upgrade

That’s OK.
What about httpd (from the message above I guess it is running) and rh-php73 services?

systemctl status -l httpd rh-php73-php-fpm

Maybe it is caused by a nextcloud app. Nextcloud log could provide more info. To list nextcloud apps you can use:

sudo -u apache scl enable rh-php73 -- php -dmemory_limit=512M /usr/share/nextcloud/occ app:list

Recently @greavette reported a problem with the Accessibility app.
