Unable to connect to Snowflake

Hi pragyajains 

You're getting a 502 Bad Gateway error from Snowflake when trying to connect via the ADBC driver. This usually points to a network issue, especially if you're using a PrivateLink endpoint (as in your case).

Here are a few things to check:

Network and DNS access
Make sure you're connected to the org network (VPN / Direct Connect) and that DNS can resolve *.privatelink.snowflakecomputing.com. Also verify firewall or proxy settings with IT.

Try connecting via the public Snowflake URL
Use the regular Snowflake URL instead of PrivateLink, just to isolate the issue.

Check your role and warehouse
Make sure the role and warehouse in the error string actually exist and you have access to them.

Driver version
Confirm that the ADBC / ODBC driver matches your Power BI version (32/64 bit), and that it's installed correctly.

Try connecting via SnowSQL / another client
That can help determine whether the issue is with Snowflake or Power BI.

If nothing works, I suggest opening a ticket with Snowflake Support. Include the full error, your region, and confirm whether you're using PrivateLink.

Thank you!

I did not have my "no_proxy" set. Once I set my proxy, it connected to snowflake. Thank you so much 🙂
