Nginx Proxy Manager: Custom locations don't work

[Iacov]

This mean that the websocket (/socket) isn't being passed.

it's weird that it's working then without the custom location code..

is it for sure, that i actually need the custom locations?
because if it were not for the documentation, i would have no indication that i need to "fix" something, as everything seems to work as far as i can tell at the moment
