Collabora Docker + Nextcloud + nginx docker, cannot open files, Collabora not sending HTTPS requests

Nextcloud shows Collabora connection is working. When I attempt to open a file in Nextcloud, Collabora logs errors like this:

wsd-00001-00600 2022-05-19 23:33:23.797926 +0000 [ docbroker_010 ] ERR  WOPI::CheckFileInfo failed for URI [https://nextcloud.example.com/index.php/apps/richdocuments/wopi/files/539_oc7tvxhh9k4b?access_token=T4Vd5Xqgf8s3lqwSrEfHhhutlAjXhLBf&access_token_ttl=0&permission=edit]: 0 . Headers:         Body: []| wsd/Storage.cpp:675

Nginx does not log the request. If I curl the URI from within the Collabora container, I get a successful response and it is logged by nginx. I installed tcpdump in the Collabora container and confirmed that no HTTPS request is being sent.

Here is my docker-compose.override.yml, adapted from one I found here:

Realized that the hostname under extra_hosts in the collabora: section of docker-compose.override.yml is supposed to be the name of the Nextcloud server. Made some other adjustments because the php-fm section is unnecessary and there have been parameter name changes in Collabora 21.11.3.6

Does it now work? For more information on what are the current configurations including: Configuration — SDK https://sdk.collaboraonline.com/ documentation and CODE Docker image — SDK https://sdk.collaboraonline.com/ documentation

Yes, it does!

I was aware of the information in the links you provided; that’s where I started. The problem was getting it to work with the nginx container in mailcow. I’m pretty new to docker and docker-compose. I figured out that I had the wrong hostname in extra_hosts by running tcpdump in the collabora container and seeing that requests were going to the wrong IP address.
