DAB fails to deploy from first try "TLS protocol version not supported"

Hello

I'm using the Databricks extension on VSCode, and when i attempt to deploy i often get this error

However after retrying once or twice it will deploy successfully.

I assume this is a networking error? can someone help explain the problem?

Databricks VSCode 2.8.0

Databricks Connect 15.4.6

Is your network blocking TLS 1.2? Databricks supports TLS 1.2 and TLSv1.3 so wondering if any of these is blocked.

I asked our network guys. turns out they needed to configure our proxy SSL bypass the traffic to Databricks. This resolved the issue.

Thanks for your input.
