Try to telnet to server ip port 8000
Check the rejected device folder under inventory
Does the server version match the client version?
How did you check that SSL is disabled on the client?
The log show network error with protocol not supported.
I agree with pschamraml that it will need to be verified that Mirage can communicate to the end point and the end point to the server. Seems to look like it is being blocked somewhere.
It appears it was the firewall on the Mirage server that was turned on. Thanks for the help.
