Not able to edit Pages in Confluence

[Vishal Srivastava]

We are getting bellow error white trying to edit Pages. We are not using any reverse Proxy.

Getting below error in Browser (Developer tool) console window:

The connection to wss://xxx.xxx.com/synchrony-proxy/v1/bayeux-sync1 was interrupted while the page was loading. batch.js:1704:267
Synchrony: Warning: reconnect (Transport.handshakeOverXhr: ws connection failed, and cross-origin-long-polling is disabled)

We had some problems with the synchrony service in some customers. Disabling synchrony maybe allows you to identify the problem

Hi @Cristian Rosas [Tecnofor] , 

Disabling Collaborative Editing allow us  to edit the Page, but after re-enabling it we faced the issue again.  We are facing this issue after upgrading our Confluence v6.5.2 to v6.13.8.

Disable Collaborative Editing while Atlassian support helps you with this issue:

We are also facing same issue, Any resolution or workaround for this issue.
Recently we have upgraded from 6.9 to 7.1.
