Custom UI + Proxy issues


I created a small forge app for Confluence with Custom UI.
I deploy it in dev and prod environment.
It seems to work well when I connect from home, but when I connect from my company, I have a big issue, the macro doesn’t work. I’m pretty sure this is because I’m behind a proxy.


How can I solve this problem ? Is it possible to deploy the custom UI in my Confluence cloud instance ?
I was thinking that sharing the app could solve the problem but when I try to share it I have the error : “Unexpected error” .

Best regards.
