I have the same problem, Jabber discovers the services over MRA, but cannot sign in. If I enter wrong password, it gives me "Wring password". The command xConfiguration did not help. Please, help!!

[Andre Castro]

What happens if you try to login with the wrong password?

What is the Expressway version you are running?

[Nishad Ismail]

When I am giving Wrong password giving me error "Your username or password is not correct"

Expressway version :8.8.1

CUCM version 11.x

From the X8.8 on, reverse DNS is required to be properly configured.

You have the same symptom I got myself a couple of days ago.

As a workaround you can disable reverse DNS verification running the command on both Exp-E and Exp-C:

xConfiguration XCP TLS Certificate CVS EnableCvs: Off

Andre,

Thank you!

This temp fix worked for me so I could keep services up until my server admins update the DNS records for reverse lookup.

xConfiguration XCP TLS Certificate CVS EnableCvs: Off
