Cloue Firewall: How to open port 6002 for Websockets?

Posted on October 16, 2019

In my Inbound Rules I’ve set these rules:

Type: Custom Protocol: TCP Portrange: 6002 for IPv4 and 6

But still if I go to https://ping.eu/port-chk/ my port is still closed!

Any ideas?

I don’t use the local firewall only the DO Cloud Firewall

Hello, @avidofood

If you’re running on Ubuntu droplet you can try to open the port on ufw and then to disable it again. I had a similar issue and this helped.

sudo ufw allow 6002
sudo ufw disable

Is you’re application already listening on this port or have an active connection?

You can also test the connection using telnet:

telnet IPaddr 6002
