I have Ubuntu server 20.04.2 + snap installation of Nextcloud 21.0.3 Snap1.
Today we had a power failure and I am not able to start the Nextcloud server.
There is running Nextcloud Maintenance mode after the reboot of the Ubuntu server for few minutes. After that, I receive " Page is not available".
SSH access to the Ubuntu server is working fine.
How can I fix it?
Thank you very much for your answer.
