Usage of web_host in config

[MaKaNu]

I am setting up a server at the moment and struggled for ours with an initial setup.

At the end, I found out, that setting the variable "web_host" was the issue.

I am absolutely fine with not setting it, but I do not understand why it caused so much trouble.

My setup

config at /etc/semaphore/config.json
pb dir /opt/semaphore

both owned by user semaphore

I launch the server as a systemdservice
