Azure AD Application Proxy

Hi All,

I have published on premises apps. User is getting the login page but when they login it's showing error 

Could Not be resolved because : net: :ERR_NAME_NOT_RESOLVED.

I have checked internal URL is working but when i trying to login with external network it's showing above error.

Regards,

After login, is the user redirected to another hostname? This host may not be published.

Are the URL used resolvable both internally and externally?   It looks to me like your DNS-server on the internal network resolve the URL, but not on the internet? 

Verify with nslookup in both situations?
