Hi I am installing opennebula 10 in Alma 9.

Front-end - Alma 9
Firedge - Alma 9
Mysql - Rocky 9

When I import Image from fireedge UI I am getting this error. Failed to open TCP connection to localhost:2633 (Connection refused - connect(2) for “localhost” port 2633)

As this topic is follow on to my previous i am getting struk here.

Port 2633 is the port where the main opennebula service runs by default. It looks like your web interface is trying to reach it but fails to do so. Make sure to properly point the one_xmlrpc to where oned is running. Make sure oned is running as well.

Try restarting the FireEdge as you configuration doesn’t point to localhost:2633. Do you get this error only. Can you do other operations in the Web UI besides image upload ?
