We have had the gateway working for months, but something has changed. We have SQL Server on one vm in Azure and the gatewway running on a seperate vm in Azure as well. The gateway appears to be configured correctly and shows good inside of powerbi, but when I try to map a datasource it fails with the error below. I have checked firewall logs, sync logs, event view logs, sql server logs, and cant find what is knocking it down.
Unable to connect: The gateway is either offline or could not be reached.Hide details

While this is a seperate isssue, the reason I had to move the gateway of the sql box is , after a pen test, we have to turn of tls1, ssl2,3 and now I cant evein install the gateway.
The on-premises data gateway installer failed to download.
The client and server cannot communicate, because they do not possess a common algorith.
