Hey Guys,
I use Nextcloud AIO and have a problem with my SSL certificates and letsencrypt. I have connected Cloudflare in front of the cloud and maybe someone can help me with my problem? Currently I cannot access the cloud interface (see picture).
Nextcloud version (eg, 20.0.5): AIO v.7.8.1
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04
Apache or nginx version (eg, Apache 2.4.25): 2.4.58
PHP version (eg, 7.4): 8.x
The ERROR
