Hi Abhay,

Here are some general troubleshooting steps and pointers to help you resolve this issue:

Ensure that you are using the correct connection configurations for Snowflake. Configuration mismatches can sometimes lead to operation errors. 

Using a single-user access mode cluster may provide a more stable connection experience compared to shared access mode, particularly after upgrades.

Keep your libraries and connectors up to date with the latest compatible versions to avoid any deprecated features causing connection errors.

If you continue to have the problem, we recommend opening a support ticket with us to investigate the issue.
