running xwiki in a vm via port 8080. From external we can use secure https via proxy, all works fine. Now I want to use the collaborative editing feature.
When I access wiki direct via unsecured :8080 Port all works like it should but over proxy not. If I access the website through https Proxy I get the message " We were unable to connect you to the realtime system." I don’t see any blocks on firewall log.
Has anyone a hint for me if I can get it working somehow and where can I point for troubleshooting?
