Editing with Synchrony will be working for some clients and at the same time not work for others while these errors are logged occasionally.
Cause
This is a server-side error logged as a result of a client-side action.
The problematic client browser has stored JWT keys that no longer match the key pair that Synchrony is currently using. Warning message is logged when they try to connect and edit.
This can result from restarting (only) Synchrony while leaving Confluence running, and then not following that up with a restart of the browser before trying to edit a page.
Solution
- Restart the client's web browser for all affected clients (clearing cache and cookies if issues persist)
or
- Restart Confluence, which will force all users to re-negotiate those keys with Synchrony at which time they will pick up the latest and start working again
