Bug with Collabora online with Nextcloud docker with the .examples docker-compose "fpm"

[Pushergene]

When i go to the nextcloud settings and click on "collabora online", i get this when selecting Built in Code Method:

Could not establish connection to the Collabora Online server. This might be due to a missing configuration of your web server. For more information, please visit: Connecting Collabora Online Single Click with Nginx(https://www.collaboraoffice.com/online/connecting-collabora-online-built-in-code-server-with-nginx/)

But there, people say that it still doesnt work and theres no comment where somoene said that it will work, and i dont want to risk something... . In config.php The Overwrite protocol is https and overwrite url (i dont know the exact same ) was http://myinstance, but i changed to https://myinstance. Still doesnt work.
When i select "Use your own server" i get:
Could not establish connection to the Collabora Online server.

I freshly installed nextcloud on my VPS with docker, i already updated these apps but still dont work.

I have UFW firewall installed.

i replaced # location ~ ^/(?:index|remote|public|cron|core/ajax/update|status|ocs/v[12]|updater/.+|oc[ms]-provider/.+).php(?:$|/) {
with
location ~ ^/nextcloud/(?:index|remote|public|cron|core/ajax/update|status|ocs/v[12]|updater/.+|oc[ms]-provider/.+|.+/richdocumentscode/proxy).php(?:$|/) {

Still not working.

I think the issue might be that it tries to access the apps folder instead of the custom_apps folder. Because i get 500 on the following url:

https://cloud.localhost.localdomain/index.php/apps/richdocuments/ajax/admin.php

Are there any workaround for this? I'm having the exact same issue.

[corod18]

same issue here

[vanantwerp]

Also have this issue

[doc75]

Exact same issue on NC19 with docker fpm container.
Indeed, it seems that xxx.localhost address cannot get resolved from inside the container (I am not a specialist).
I tries to put the IP address of my host (instead of cloud.localhost), it does not raise anymore the log mentioned above, but still it does not work.

I've left some comments what you need to do in order to get the built-in CODE server to run at #1896 (comment)

Closing since this isn't really an image matter.
