Document Server not connecting to NC

[Chris]

I installed a Nextcloud cloud server and a OnlyOffice document server both as headless Virtualbox VM on the same host.

The OnlyOffice document server installation was followed from here: https://api.onlyoffice.com/editors/owncloud
as indicated by the Nextcloud app user/admin guide. The installation consisted of the docker image.

Both the Nextcloud and the OnlyOffice document server work fine but I cannot integrate the Document server on the Nextcloud server. I am getting a timeout error.



I can ping the OO server from the NC server and vice versa. All firewalls are disabled.I am using static DNS (in /etc/hosts) and I am accessing all my nodes from the LAN. May I get some hints on how to debug please?

Hello Chris!
What about logs?
Please more info about ip, domains, screenshots. In common it's because of wrong URLs. Servers cannot communicate with each other.
