I think I found a workaround @transocean @Tiago . It seems that Collabora and Onlyoffice don’t like internal Nextcloud IPs anymore, even if there are configuration options for both but they didn’t work in my tests.
In my network setup both ports 80 and 443 are forwarded to the NS8. Hairpin NAT may need to be enabled on the firewall for the port forwardings to get connected correctly to Nextcloud instead of the firewall on the NS8…
So I added a DNS entry for my public IP (11.22.33.44 in the example) to the public Nextcloud FQDN on the Rocky host in /etc/hosts:
11.22.33.44 mynextcloud.example.com
Both services need to be restarted to apply the new hosts:
runagent -m collabora1 systemctl --user restart collabora
runagent -m onlyoffice1 systemctl --user restart onlyoffice
After saving the settings for both apps in the Nextcloud admin settings they should be able to open documents again.
I’m going to dig deeper to find a better solution…
EDIT:
Maybe it has to do with the recent podman changes: Rockylinux basic update, app on webserver does not start - #49 by stephdl
