Jabber for Windows 10.5 "Can not communicate with server" error

[richard Beck]

When doing the automatic provisioning of Jabber some users receive a "Can not communicate with server" error. I looked at the log files and Jabber is not able to access the UDS information for the user that is logging in. 

In the error logs there is a permission error accessing

http://callmanagerip:8443/cucm-uds/user/userid

This issue occurs with random users.

What do I need to look for the call manager for that user to resolve this issue?

When we compare a broken user to a working users things *seem* to look the same.

Thanks

Figured this out. User didn't have the "Standard CCM End Users" Permissions assigned.

@ richard Beck   good answer your answer is right

Though this was not your error, if connecting via MRA, if your NTP is not working on at least your VCS-E, you will receive this error, shown as an HTTP 502 error in the logs.
