MRA iPhone Jabber client wont authenticate with CUC

[pedrop]

Hi,

I have a strange issue where CUC authentication works for the following:

local login with desktop Jabber

MRA login with desktop Jabber

But when I try MRA login with iPhone Jabber I cannot authenticate with CUC.

When I log in to the iPhone jabber I get the notification saying the credentials are correct. If I enter the credentials nothing happens.

I don't see anything in the Expressway-C logs expect the notification that the 'http://<CUC_IP>:7080/vmevents/cometd/connect' request was allowed.

Any ideas? All other services are working fine.

Not sure about your particular case but maybe you could go nuclear on it if cannot solve:
