I can't access Cloud9 on port 8081 running on Google cloud platform.

I am sure the application is running on that port and applications on the same machine on other ports (e.g. http://xxx.xxx.xxx.xxx:3000) are accessible correctly, so this doesn't seem to be an issue with the iptables settings.

I receive no response from the server http://xxx.xxx.xxx.xxx:8081/.

Google Cloud Platform configuration:

Allowed protocols and ports include tcp:8000-8089

IP Address set up as static and external

Command used to run Cloud9:

node server.js -w /home/workspace -l 0.0.0.0 -p 8081 -a username:password

The problem was that I have accidentally added some Target tags in the Google cloud firewall settings (Networking > Firewall rules).

Removing those tags solved my problem, I just use the default Apply to all targets setting.
