No socket could be created socket -error

That message indicates that some other program, such as a web server, is using port 80 on the same Raspi.

You can either stop the other program or edit the file SIP/data/sd.json
Change the line "htp": 80 to something like "htp": 8080

That should allow SIP to run.

If you stop the other program you can change the port setting on SIP's Options page.
