The issue you are facing:
After upgrading Nextcloud and PHP, and installing a couple of new Nextcloud apps, the Nextcloud page will no longer load. Accessing the Nextcloud site now results in:
503 Service Temporarily Unavailable
Nginx is working without issue.
PHP is working without issue.
MySQL is working without issue.
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Upgrade Nextcloud from 17.x to 18.0
- Upgrade PHP from 7.3 to 7.4.1
- Install/enable Nextcloud “Notes” and “Tasks” apps
- Reboot server
