swagger via azure app proxy

[Kazz]

Hi,

Has anyone attempted to expose swagger to the outside using azure application proxy? I am getting "This page isn’t working"
HTTP ERROR 500, when trying to access https://myveeambr123-myorg.msappproxy.n ... index.html
500 shows up after I pass Azure MFA, instead of the swagger page.
App Proxy is configured to redirect https://myveeambr123-myorg.msappproxy.net to https://myveeamvb123.myorg.local:9419

What Advanced App Proxy settings would you recommend turning on / off for swagger to work while being proxied ?
Backend Application Timeout
Use HttprOnly Cookie
Use Persixtent Cookie
Translate Urls in header
Translate Urls in application body
Validate Backend SSL certificate

Any help is greatly appreciated.

Thanks
