Im using nextcloud and collabora behind an nginx proxy in a single docker network. I keep getting errors and cant connect collabora to nextcloud.

Hitting https://office.exampe.com responds with OK so i can tell its working. Also the admin logs in but I never get any logs from that.

it looks your Collabora can’t reach Nextcloud using the URL above.
Nextcloud provides good troubleshooting guide:

https://docs.nextcloud.com/server/latest/admin_manual/office/troubleshooting.html

This is a good link. Thank you. Going to take a look later tonight. It would be odd that it cant reach nextcloud as i have been using it for years. But it may be some internal container network stuff going on

Ok so i took a look at the doc, Im writting down the commands i used so that it may help others. I already sorta knew it would be collabora trying to reach nextcloud as you mentioned so i skipped checking the other way around.

docker exec -it collabora bash
 curl -v https://cloud.example.com/status.php
*   Trying 172.33.0.10...
* TCP_NODELAY set
* connect to 172.33.0.10 port 443 failed: Connection refused
* Failed to connect to cloud.example.com port 443: Connection refused
* Closing connection 0
curl: (7) Failed to connect to cloud.example.com port 443: Connection refused

This means its trying to connect internally and bypassing the nginx container which handles ssl on 443. Just have to find a way to make it route through nginx in the container.

I have figured it out I actually had hostname: cloud.example.com in the nextcloud compose and it was using that internally instead of routing out through nginx. I removed that and it now works.

I’m not using Docker but I have the same issue. First of all my system wasn’t resolving cloud.example.com (who knew - Ha). I changed /etc/hosts to accept and resolve it to 127.0.2.1 which it did but now i’m throwing a 404 error. What’s the real fix for this?
The trouble shooting guide doesn’t go into this specific error.
Thanks for your help in advance.

Nextcloud Office works btw. The error is just disturbing me because it keeps showing up in the logging file
