Introduction

This document describes the most common Jabber login issues and how to correct them.

Prerequisites

Requirements

Cisco recommends that you have knowledge of Cisco Unified Communications Manager (CUCM) and Cisco Jabber.

Components Used

The information in this document is based on the listed software versions:

- Cisco Unified Communications Manager (CUCM) 14.0.1 SU2

- Domain Name System (DNS)

- Cisco Jabber 14.1.3

- Windows 11

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Common Problems and Solutions

The errors listed in the document are the most common errors seen when a login failure occurs when using Cisco Jabber.

Untrusted server. No services discovered

Login Error: Untrusted server. No services discovered.

CUCM Certificate Failure

The untrusted server error is displayed when the operating system the Jabber client is installed on does not trust the Certificate Authority used to sign the CUCM Tomcat certificate.

Solution

- Self signed CUCM Tomcat Certificate

- Upload the self-signed certificate to the user machine as a trusted certificate authority.

- Certificate Authority (CA) Signed Certificate

- Verify the certificates root Certificate Authority is a trusted root on the operating machine running Cisco Jabber.

Cannot find your services automatically

Login Error: Cannot find services automatically.

DNS SRV Failure

During initial login, Cisco Jabber queries for DNS service records to automatically detect and locate services on the network. If these queries fail the Cisco Jabber login process fails due to services not being identified.

Solution

If logging into Cisco Jabber on the local network or over VPN, verify the operating system running Jabber can successfully query the _cisco-uds._tcp.domain.com DNS SRV record. When logging into Cisco Jabber over Mobile Remote Access (MRA) verify the operating system can successfully query the _collab-edge._tls.domain.com DNS SRV record.

For assistance with configuring the DNS SRV records used by Cisco Jabber please refer to the On-Premise Deployment Guide for Cisco Jabber.

Home Cluster Not Found

The NO_HOME_UDS_FOUND error in the Jabber logs indicates the Cisco Jabber was able to discover the DNS service records but failed to find the CUCM home cluster for the Jabber user.

Solution

Navigate to CUCM Administration > User Management > End User. Select the user and verify they have the "Home Cluster" checkbox enabled in CUCM.

CUCM End User Home Cluster

Cannot communicate with the server

Login Error: Cannot communicate with the server.

DNS Hostname Failure

During login, Cisco Jabber connects to CUCM to retrieve home cluster and configuration information. When connecting to CUCM Cisco Jabber performs DNS A record lookups for the CUCM nodes. If these queries fail the Cisco Jabber login process fails as Jabber is unable to communicate with the CUCM nodes.

Solution

If logging into Cisco Jabber on the local network or over VPN, verify the operating system can successfully query each CUCM nodes DNS A record. When logging into Cisco Jabber over Mobile Remote Access (MRA) verify the operating system can successfully query the Expressway-E DNS A record.

End User Permissions

During Initial login, Cisco Jabber performs a home UDS lookup for the user that is attempting to login. If the login user is not assigned sufficient privileges the login attempt fails.

Solution

Navigate to CUCM Administration > User Management > End User. Select the user and verify they have the "Standard CCM End Users" role is assigned to the end user.

CUCM End User Roles

Your Username or Password is not correct

Login Error: Your username or password is not correct.

Authentication Failure

During initial Cisco Jabber login, users must be authenticated to be authorized for services. If authentication fails the Jabber login attempt fails.

Solution

Verify the Jabber username and password are correct. If username and password is correct verify that the Jabber user can login to the CUCM end user web interface. If login to the CUCM end user web interface fails verify that the authenticating LDAP is reachable from CUCM and the correct user search base is defined.

Certificate not valid

Login Error: Certificate not valid.

SOAP Certificate Failure

During Initial login, Cisco IM and Presence enabled users authenticate with SOAP services on IM&P. If the Cisco IM and Presence tomcat certificate chain is not trusted by the operating system the login attempt fails.

Solution

Verify the operating system running Jabber trusts the Cisco IM and Presence tomcat certificate chain.

XMPP Certificate Failure

During Initial login, Cisco IM and Presence enabled users connect to XMPP services. If the Cisco IM and Presence XMPP certificate chain is not trusted by the operating system the login attempt fails.
