CODE docker-compose: Login credentials not working

Hi all,

I have the following docker-compose.yaml to set up Nginx, Nextcloud and Collabora. This is my first attempt at using docker-compose, and really the first major go at using docker for something other than a tutorial.

version: '3'

Nginx and Nextcloud are working really nicely, but Collabora not so much. I have Nginx Proxy Manager set up for:

nginx.domain.com
nextcloud.domain.com
collabora.domain.com

The proxy for Collabora is set up as follows…

Domain name: collabora@domain.com
Scheme: https
Forward Hostname/IP: code
Forward Port: 9980
Cache Assets: disabled
Block Common Exploits: enabled
Websockets Support: enabled

SSL Certificate (issued by Let’s Encrypt)
Force SSL: enabled
HTTP/2 Support: enabled
HSTS Enabled: enabled
HSTS Subdomains: disabled

When I navigate to collabora.domain.com, I get the OK message.

When I navigate to collabora.domain.com/loleaflet/dist/admin/admin.html I get a login form pop up, but when I enter the credentials passed into the docker-compose file, it just shows me the login form again. No message or anything.

When I try to link up Nextcloud to the CODE server using collabora.domain.com, I get the Could not establish connection to the Collabora Online server. message.

Any ideas what I’ve done wrong here?

I don’t seem to be able to edit my original post, however I found that removing special characters from $ COLLABORA_PASSWORD did the trick. I can now log into the admin page.

I am still unable to link Collabora into Nextcloud though. :frowning_face:
