[Bug]: Running OpenSign on custom port does not work - api calls ignore port

[kuermayr-inola]

Issue Description

Hello,
we added a custom port to the opensign URL via .env.prod config today.
The port is open in our firewall and the tool can be accessed from the public internet (dashboard can be reached).
All good - BUT
in the document creation dialog (and probably some other places) opensign calls for the api and does not include/ignores the configured custom port. The api call goes into timeout because 443 is blocked by the firewall.

Internally within our network opensign works fine.

Is there any possibility to enforce the port for the api calls?

mentioned api call which fails:
