MCP Gateway Timeout

[orathee]

My local MCP server connected to tableau cloud is showing gateway timeout error randomly after 1-2 days. Once its timeout, my application won't able to connect to mcp server unless i restart the mcp server. What is the reason for this ?

tableau-mcp v1.18.1 streamable HTTP server available at http://localhost:3927/tableau-mcp

It happened again today. I was chatting with my app and suddenly my app show session expired. I checked the MCP server and its showing same Gateway timeout in between of session.

@anyoung-tableau Any thoughts here ?

That's not a blocking error, but looks like your machine can't connect to prod.telemetry.tableausoftware.com so the telemetry can be sent. You should probably disable telemetry if you want to silence the errors. https://tableau.github.io/tableau-mcp/docs/configuration/mcp-config/env-vars#product_telemetry_enabled

Thanks but why once this error appears in cmd terminal then my app no longer able to connect to tableau cloud or mcp. The only option is to restart the mcp server to work it again. Is this expected ? And why this error is random. Sometime it come in 1 day and sometime in 2 days.

Hmm, maybe this is a more general loss of internet connectivity then. If you can't connect to both the public telemetry endpoint and Tableau Cloud, I'd think your ISP or VPN is down.
