Jabber Client and Firewall Decryption

We decrypt SSL traffic at the firewall, and nearly all applications are fine with it, but Jabber seems to have a problem with it. The Windows computer that it's running on is domain joined and trusts our organizational root CA, which is used by the firewall to re-encrypt SSL. As long as the client trusts our CA, it should be fine. If Jabber either does not honor the Windows certificate store, or if it's looking for a specific certificate, it would fail. We would like for Jabber to function, but we can't make broad exceptions to decryption policy to suit one application. Can Jabber be configured to function with a firewall that decrypts? Can I tell Jabber to trust my organizational CA, or if that's not the cause, what can I do? All I know is that if I make a decryption exclusion for the test computer, Jabber runs; otherwise it does not.

Hi blntskul,

Which Jabber client are you using; Cisco Jabber Video or Cisco Jabber (Messenger Client)?

If you are using the messenger client, then please redirect your issue to the following community:


If you are not using the free service, and using the Enterprise version registering to your own VCS-C/E infrastructure, then please repost your issue here:


If you are using the free beta service, then the only thing I can say is to follow the firewall ports per this post:
