Setting SFTP server in Azure to not generate new host key upon reboot

When setting up an SFTP server is it possible to configure it to not generate a new host key upon reboot?

At which end of the SFTP link - the supplicant, or the Azure end?

We had someone setup an SFTP server on  an Azure server. When the server rebooted the host key changed. That stopped of of our transfer programs written in Powershell from connecting. So it is on the Azure side.I assume the supplicant side is the client side?

This SFTP server is out of my contriol. I was told it was sitting on an Azure server. All I know it that it was rebooted last week and right after that none of the Poweshell scripts worked until I updated the host key.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Perhaps the SFTP server was redeployed instead of being rebooted?
Without knowing how the SFTP server was deployed it is "difficult" to comment on what caused the new key.
