Thanks for the PR!

Please remove nignx and just use the Coolify proxy if that is possible. Also test the template in detail as it is not working for me.

Some service log shows some env are not set:

Closing this in favor of #6492 , where the same service is added and works out of the box.

Thanks for the PR!
