Struggling to Disable Encryption

Hello, I am struggling to disable encryption. I want to disable encryption because I keep getting the Encryption not ready: multikeyencryption failed error:0480006C:PEM routines::no start line error and don’t know how to fix that.

In trying to disable encryption I try to enable maintenance mode I run sudo -u serena php /home/serena/web/(domain)/public_html/occ maintenance:mode --on
and I get the output of Could not open input file: /home/serena/web/(domain)/public_html/occ
The Nextcloud user is “serena” and the Nextcloud directory is “/home/serena/web/(domain)/public_html”
These are the defaults set up by the Hestia Control Panel.
Why do I keep getting this error and how do I get occ to work?
I use Nextcloud Hub 3 - 25.0.1, Ubuntu Server 22.04 LTS, PHP 8.0, and Hestia CP 1.6.11.

Can someone please help me? My nextcloud is unusable until I find some way to fix this.

It seems that Nextcloud doesn’t want to fix this until the new Nextcloud 26 release in March 23. Downgrade to Ubuntu 20.04. Then the ssl should work.
