Confluence mixed content ( apache ssl)

[alser84]

Greetings!

My env:

Conflunce 6.15.6 ( 100 users) on Windows 7 with apache 2.4. 39 Win 64 reverse proxy.

I'm trying to set up access to Confluence by https. And can't do this.

When i try to edit page i get:

Mixed Content: The page at 'https://confluence/confluence/pages/viewpage.action?pageId=565872161' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://confluence/synchrony/heartbeat?_=1562167060607'. This request has been blocked; the content must be served over HTTPS.

How move synchrony to using https connector?
