My MAAS server has been running for several months, building OpenStack cloud configurations and tearing them down, but then it starts giving the error message
Unable to connect to: ws://hostname:5240/MAAS/ws
when going to to the node list.
I have tried rebooting the server, reconfiguring maas-region-controller, everything I can think of. I can telnet to the port and something is definitely listening on it.
How do I recover from this? My only successful method in the past has been to wipe the disk and do a total reinstall and reconfigure, starting over. This happens regularly.
I needed to make certain that port 5240 was available between my desktop and the maas server. It was not open which caused the failure. After making port 5240 available it worked fine.
Edited: You can access it directly from http://hostname:5240 I successfully accessed it directly even though http://hostname/MAAS/ giving those errors.
