Installed on debian server.  Can not connect remotely.

Used netstat to checking that it is listening on the right port:

netstat -nlp | grep 6000   
tcp        0      0 127.0.0.1:6000          0.0.0.0:*               LISTEN

The web hosting company says that the application should be listening on 0.0.0.0:6000 rather than 127.0.0.1.   But I can't find anywhere to change this in the settings.

Figured it out.
 Fixed with:

sudo openproject config:set HOST=0.0.0.0

Hi Rob,

in a packaged installation, the web server is responsible for handling outside connections. The internal application server on port 6000 should not be made public. What is your setup that the web server does not handle this? Did you not choose to install Apache or does it listen on a public interface?

Best,

Oliver

Thank you very Rob! With your post I solved an issue I had in my implementation of Open Project. I posted my scenario on https://community.openproject.com/topics/11952
