no upgrade to Hoobs 4 available, wrong port ?!
**Description**
I want to migrate hobbs 3.3.12 to version 4. Unfortunately with no upgrade is offered. I had read that port 80 is required. Strangely, the port 8080 is deposited as standard with me. if I change the port from 8080 to 80 via the hobbs web gui and restart hoobs, the gui gets stuck and can no longer be used. Via putty I can then set the old port 8080 in the config.json again, after a reboot the gui can then be used normally again. does the change of the port still have to be made somewhere?

**Version**
3.3.12
