Can not connect to the streaming server could not write data to host: Connection refused in write()

Hi, we have installed LibreTime but have issues with connecting the stream. We get this message that says:

"Can not connect to the streaming server

could not write data to host: Connection refused in write()"

When we first set it up the stream, it connected, but after a restart of the computer it can no longer connect.

All our status reports have green checks.

Between it working and the restart the only changes we did was change the password for the admin account from admin/admin to something safer and change the Port Forwarding adress in our router so that LibreTime could be accessed remotley. After that everything worked fine until we restarted the computer.

Is the Icecast2 Server running ?
http://HOST:8000

Had that happening that it did not start after reboot.

Other situation i had:
I had the Networking stuff on the host server so hardly modified that LibreTime (Liquidsoap) could only connect to the IP of the System (10.X.X.X) and not via 127.0.0.1 or localhost.

Just a few ideas, maybe they help.
