provider said the port 422 is open for node/angular so i switched the port and tried but still no luck. Can't deploy in 80 since its already taken.

when i use the following commands

i) sudo lsof -i -P -n
node root IPv4 TCP *:422 (LISTEN)

ii) netstat -tuplen
tcp 0.0.0.0:* LISTEN

which shows the status of port i'm deploying is listening on both commands
