It would appear that you have something already running on your HTTPS port. I'm not familiar with Google Cloud Platform and your question lacks a tremendous amount of detail but; you can try to run either of the following commands to determine if something is already running on port 443

sudo lsof -i -P -n | grep 443

or 

netstat -tulpn | grep 443

  • Nginx Listening bur Web UI showing error. – viswanath Oct 24 '17 at 15:42
  • Can you post your nginx config file and possibly the output from your access.log or error.log? – Sam K Oct 25 '17 at 12:39
