I am facing with this connector. It works 100% of the time from my desktop but when i try from an Azure VM it only randomly succeeds. I did a Wireshark trace and can see when it fails, the client tries to do a TLSv1 handshake and the Databricks Service detects this and sends back a reset. Randomly it will try with v1.3 and then the connection works. I have tried setting the http_header to tls-version : TLSv1.3 but it doesn't seem to have any effect

in this screen shot you can see a success and failure side-by-side
