Error when deployed from Azure

[pnwguy]

I got this working fine inside our corporate network, but deployed via Azure Web App, we are getting the below error using Authentication Mode 2:

<Error>
<Message>The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state.</Message>
</Error>

Networking guys say everything in Azure is connected fine to our on-prem environment.

Is there any suggestions to consider when deployed to a web app accessing on-prem?

Hi,
You need to setup the Azure Hybrid Connection.
https://docs.microsoft.com/en-us/azure/app-service/app-service-hybrid-connections

Under your Api App in Azure click on Networking and follow the wizard for setting up the Hybrid connection. It will download a service and it will sit on prem.

Thanks, we have Azure VNet + VPN to our corpnet, which works for our database connections. Is it because AX uses TCP to access the AOS, is this why Azure Hybrid Connection is needed?

hi.
No need for any VNet/VPN.
Azure Hybrid Connection takes care of all that.
As the link from docs says:
"It normally does not require firewall holes. The connections are all outbound over standard web ports."
I have implemented it at a number of customers and it was the case. Very easy to set up.
Just needs the azure global administrator to do (i think my memory is right).
