Help Setting Up Nextcloud Office

[RebelLion1519]

Hello, 

 

I have been trying to set up an online office suite in Nextcloud for a while and I've gotten nowhere. I'm running the Linux Servers Nextcloud container behind the SWAG proxy, Nextcloud is accessible at nextcloud.mydomain.com. I've installed the Collabora CODE container and also have it behind the proxy, at collabora-code.mydomain.com. When I enter my document server's IP and port or domain link in Nextcloud, I get "Could not establish connection to the Collabora Online server." If I try to go to the Collabora CODE web UI, there's a dialog to enter my username and password, and it just loops, enter credentials, dialog box remains. Obviously I'm missing something somewhere, but I don't know where to go from here. 

 

Thanks!
