[Network Application Gateway] pickHostNameFromBackendAddress cannot be set as true

Question

[Network Application Gateway] pickHostNameFromBackendAddress cannot be set as true

ms-zhenhua opened this issue 2 years ago · comments

The ApplicationGatewayBackendSettingsPropertiesFormat.pickHostNameFromBackendAddress is defined as a boolean. However, when it's set as true, I got the following error from the Azure side.

Failure sending request: StatusCode=400 -- Original Error: Code="ApplicationGatewayBackendSettingsPickHostNameFromBackendAddressNotAllowed" Message="PickHostNameFromBackendAddress cannot be set to true for BackendSettings '/subscriptions/******/resourceGroups/acctestRG-000000/providers/Microsoft.Network/applicationGateways/acctestag-000000/backendSettingsCollection/acctest-vnet-000000-be-st'

@ms-zhenhua I tried to collect the HAR traces while performing the same operation from Azure Portal and that seem to have worked. Below is the Request Body it used. See "pickHostNameFromBackendAddress":true in the below request body:

Could you please try the same via this REST API call and check if that helps ? Awaiting your reply.

Hi @navba-MSFT, the pickHostNameFromBackendAddress you are testing is under ApplicationGatewayBackendHttpSettingsPropertiesFormat. There is another pickHostNameFromBackendAddress defined under ApplicationGatewayBackendSettingsPropertiesFormat which cannot be set to true

@ms-zhenhua I had a discussion with the AppGW PM team and they informed that, Since you are internal to Microsoft, they will coordinate with you and work on this further.

If you need any further assistance on this let me know.

@ms-zhenhua Since the PM team has informed that they are working on this offline with you, we will now proceed with closure of this github issue. If you need any further assistance on this issue in future, please feel free to reopen this thread. We would be happy to help.
