[BUG] Subfolder path does not work

[Lukakeiton]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When setting SUBFOLDER=/doublecommander/ (both slashes included), you get a html plain text like this one: "Cannot GET /doublecommander/". If I remove SUBFOLDER=..., then I can access to container.

Expected Behavior

Get the UI with proper base URL.

Steps To Reproduce

Adding SUBFOLDER=/doublecommander/ to yaml

Environment

- OS: OMV 7.0.4-2 (Sandworm)
- How docker service was installed: omv-extras, compose included

CPU architecture

x86-64

Query - have you put the container behind a reverse proxy such as swag?

Closing due to inactivity, I'm presuming you are not actually RP'ing this application leading to it behaving weirdly when setting this environment.

Would recommend trying to access it without that subfolder being set and seeing how you get on. Then try the RP. Join us in Discord for further support with using our containers.
