Issues configuring synchrony for confluence data center

Question

Hello,

Testing out Confluence Data Center setup on a local VM. It's an upgrade from Confluence Server to Data Center to be exact. The upgrade was fairly straight-forward, just followed the instructions and it just worked. However, running into issues with synchrony - no big surprise there.  ;)

I followed the instructions and created a script to launch synchrony as a process, I've also changed the default port for synchrony - on the surface everything is great, in the collaborative editing admin panel it's all "green", heartbeat returns OK, however, the moment I try to create/edit a page things turn sour - spinner on the edit button for a minute, then it times out and goes into the edit with the following message:

Here's the log messages related to this from atlassian-confluence.log:

Specifically if would be awesome to know what these two mean:

* Could not verify  AppID/Secret for real-time collaboration service
* This instance could not be registered with Synchrony

Not sure what I'm doing wrong here. If you have some insight to share, please do.

Thanks in advance!

Team,

I was able to fix this issue with re-creating the JWT Private and Public keys and configure the same within confluence.cfg.xml file.

Collaborative editing is working.

For additional information on generating JWT keys, please refer to the below link:

Thanks,

Hello,

I had the same problem. For me Step #5 from the atlassian docs helped (had the nonproxyhosts configured wrong)

Kind regards,

Team,

Can someone help by providing a fix or workaround ? we are also seeing the same error after migrating from Confluence Cloud to Confluence Server (6.4.2).
