can't edit document when enable synchrony

[kang]

when I enable synchrony, I can't create or edit a document.

I use chrome debug mode .

It shows POST 404 "http://mydomain.com/synchrony-proxy/v1/data/Synchrony-58256301-093c-3f38-97a8-721f170485da/confluence-45547527?state-at=@head&state-format=type-tagged&rewrite-request=true&cached=true"

My confluence version is 6.15

I didn't use nginx as a proxy.I use tomcat directly.

Here is my server.xml

<Server port="8000" shutdown="SHUTDOWN" debug="0">
<Service name="Tomcat-Standalone">

Hi @kang

I recommend you create a support ticket directly with atlassian.  We had similar issues with synchrony and we had to get on a bridge with atlassian support to resolve it.
