APNs for Jabber stopped working overnight

[PeterJames21]

We currently have Jabber installed on multiple iPhones and Androids that we use for internal calling. This morning the only calls that were going through were on the Androids and those who have it on their PCs. The iPhones would only receive calls if the phone was unlocked with Jabber open or with Jabber still open in the foreground after locking. Once Jabber goes to the background or is closed, it doesn't receive any calls. Uninstalling, upgrading, reconfiguring do not help. We're pretty sure something is up with the push notifications. It has been working pretty good for years now and there has been no change to our servers.

Hey Peter,

as I noticed a discussion in a Webex Space, there might have been a certificate change in the Cloud.

Solution could be to generate a new voucher and restart APNS service or refresh the token manually.

What you also can try is the following:

1. Disable APNS
2. Enable APNS again
3. Restart Tomcat on all servers
4. Restart APNS service
5. restart Cisco Management Agent Service

I haven't read anything about that somewhere else, so it's just the information I have from a partner space.

I hope it helps tough.

Our organization started to receive RTMTs for failed Jabber push notifications yesterday. After submitting a TAC case we were informed by TAC there is a global issue on Cisco's end. We are in the process of exchanging information with TAC and have not yet gotten a resolution. I would suggest submitting a TAC case.

Received word from TAC:  

We have been facing issues with APNS along customer's sites, the thing is that certificate chain was updated in Cisco Cloud on October 26th, so now we are using new Root certificate - IdenTrust Commercial Root CA 1 CUCM APNS documentation updated with that requirement.  

They sent the cert with instructions to install.  Tested it out and APNs for Jabber are now working.
