If yes, please take the note of the port number. - Open Configuration interface
Change the occupied port to a different one, for example 28005 (all other conflicts need to be revised). Apply changes.
- Wait until the interface closes by itself (it might take longer than 5 minutes)
- If you still exhibit the issue, please repeat the above steps until the problem is solved (try different ports; check error messages)
Temporary testing steps
- Follow the above steps 1-4
- Open the Terminal and run lsof –i: XXXXX (where XXXXX is the port number occupied)
- Find the PID of an application occupying the port and run kill -9 YYYYY to close the process.
- Wait untill all processes in conflict are closed and restart the ViewPower
