Access to gadget not done locally and not configuration through mutual SSL

[Yoram (the yoz)]

Hi,

My Confluence server sits behind an Apache Reverse Proxy with Two Way SSL. Confluence tries to access a local page (localhost) through the external domain which means going through Apache RP and getting blocked. Shouldn't it goes through 127.0.0.1?

Hi @Yoram (the yoz)

If you are still having issues, I recommend you open a ticket with atlassian support and provide the support zip files for analysis.
