Hi, I am currently setting up an MCP Server and it uses SSE (Server Sent Events) to communicate. I get all sorts of timeouts and disconnects, and the docs state that running behind a proxy requires additional configuration:

https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-langchain.mcptrigger/#running-the-mcp-server-trigger-node-with-a-reverse-proxy

How do I do that configuration with godoxy?

Thanks

GoDoxy flushes on every read, so I suspect the problem was from compression. Just pushed v0.13.5 which added a new disable_compression option. Try this label:

proxy.{alias}.disable_compression: true

Thanks for your prompt answer and looking into this.

Unforntunately, I still can't establish a connection. But the problem is more likely on another place, as multiple sites have reported the same problem:

No problem, please let me know when it's fixed so I can confirm it's not GoDoxy's issue. Thanks.

We just released Supergateway v3.1.0 that should address protocol version mismatch errors. Let me know if this is still not solved for you if you use Supergateway.

@yusing Yes, thank you. Together with the updated version from supergateway and the disabled compression in v0.13.5 I got to get n8n mcp server working behind godoxy as proxy.

Thanks everyone.
