Hello

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

"Error: Post "https://adb-xxxxxx.xx.azuredatabricks.net/api/2.0/workspace-files/import-file/Workspace%2FUsers%2FXX...": remote error: tls: protocol version not supported"

However after retrying once or twice it will deploy successfully.

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

Hi @sparklez,

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.
