Sunstone page failes on a RunTimeError from the first time

Community Support GUI - Sunstone

I’ve finished installing opennebula, and I tried to open the sunstone web page on 0.0.0.0:9869 but it never opens. It shows application error.
When I checked the sunstine.error :

`== Sinatra has ended his set (crowd applauds)

I also checked if any other app using same port but found nothing but:

$ sudo netstat -anp | grep ruby

I guess I knew where the problem is, but I don’t know how to solve it.

Hi!

Most likely an issue with an already running sunstone process. Reboot the server, make sure there are no ruby processes running, and try again.

Hi @tinova,
I did reboot the PC but nothing changed.
should I kill process on 127.0.0.1:5030?
I killed it and then I checked site but nothing happened even when I tried restarting the service and rebooting PC after, but results are also the same.

5030 is onegate’s port.

the error message you are getting is due to the port being used.

can you confirm that after restart the following comes empty? “sudo netstat -anp | grep ruby”. Also, that after seeing an empty list, you get the same failure starting sunstone?

When I did restart, and tried this command, more ports where in use with ruby.
but unfortunately I re-installed the opennnebula and I am stuck with another issue.
The opennebula service fails to start
