Hi,

I am using the docker compose file from Docker Compose for Nextcloud + Collabora + Traefik? - #5 by wwe.

Except for the following error:

Could not establish connection to the Collabora Online server.

Failed to connect to the remote server: Client error: GET https://myhost.com/hosting/discovery resulted in a 404 Not Found response: 404 Not Found

404 Not Found

nginx</c (truncated…)

I can access https://myhost.com/hosting/discovery in my browser, while configuring Collabora, however, I get the error above.

Any idea how I can start debugging?

Thanks,
Bart

Please review Collabora integration guide for troubleshooting steps. Often network alias (splitbraindns) workaround helps in docker Probably DNS help with NC Docker + Collabora + Wireguard tunnel

Thanks! Indeed had to check the DNS, in particular, the nextcloud image has to resolve the call to myhost.com (the Collabora instance), which it cannot with the docker compose from the link.

When I now try to open a docx file, I get

Unauthorized WOPI host. Please try again later and report to your administrator if the issue persists. Authorization error was: ‘self-signed certificate’.

Disable certificate validation was enabled. Is that issue related to the Let's Encrypt certificates that I’m using?

Your feedback is appreciated!

Regards,
Bart

ps Is anyone interested in an updated docker compose if I get this up and running?
