Hello,
We are facing below issue while trying to click on Edit option.
This is occurring for every browser. Have checked Base and Access url, they are the same. Also have restarted the synchrony.
We have apache installed withProxyPass and ReverseProxy are set for '/synchrony-proxy'.
The same value(/synchrony-proxy) is set as Context path for synchrony in the Confluence (server.xml)

Please let us know.
Regards
Sayak
