Collaborative editing not working Edited

[rishi]

Hi

I have upgraded to Confluence 6.4.0 and cannot edit pages in Collaborative mode. I get this message

This page is taking longer to load than usual. Give it a few moments, then try refreshing. Still having issues? Contact your Confluence admin.

and logs in the atlassian-synchrony.log file:

{"synchrony":{"message":"synchrony.middleware.memorize-response [info] request for static resource","cache-key":["0.0.0.0","/synchrony/resources/js/vendor/sockjs.min.js",null],"ns":"synchrony.middleware.memoize-response"}}

{"synchrony":{"message":"synchrony.middleware.memorize-response [info] request for static resource","cache-key":["0.0.0.0","/synchrony/resources/js/synchrony.min.js",null],"ns":"synchrony.middleware.memoize-response"}}

Upgraded from what version? Did collaborative editing work before? The logs you provided have no relevant detail. Please provide portions of the atlassian-confluence.log instead.

We upgraded from Confluence 5.10.1

I also upgraded from 5.10 to 6.1 for both staging and production environments.  Collaborative editing works in staging, but not in production.  I compare the log files, the atlassian-synchrony.log, and the error seems to be in these 2 lines:
