Why when i hit application gateway's public ip, i get redirected to app service url ?

[MohamedBenighil]

Hello Teams,

i created an application gateway with app service as backend pool, but when i hit the public IP of AG, i get redirected to app service's URL with 80 as port (ie i get redirected to somthing like : https://benighil.azurewebsites.net/:80)

The expected behaviour is : When i hit the Public IP of application gateway, i get the page of the app service in question wihout redirecting to https://benighil.azurewebsites.net/:80)

Any help please ?
