Error DK0031: Port 80 and 443 is used

DevKinsta Bug Reports

Update: I managed to complete the installation by killing all processes on port 80, however, I have no idea if this is a long-term fix (presumably not).

Mac:

# find & kill processes which are using port 80
sudo lsof -i tcp:80 | grep LISTEN | awk '{print $2}' | xargs kill -9

Windows:

# find processes which are using port 80
netstat -ano | findstr :80

# kill process by PID. replace "<PID>" with result from the above command.
taskkill /PID <PID> /F
