Render and Railway deployments not connecting using MCP Client in n8n #2

Description

@lvxn0va

Works fine in local Claude and Cursor however when installing the GHL MCP server on Render or Railway workpaces, and using an n8n workflow with a simple MCP client chat trigger and SSE link, the endpoint connects but the GHL side does not respond.

Manual chatting with the MCP is alright however with over 200 tools in thsi MCP, automation is the key.

Web Searches indicate the cuprit may be compression on the /mcp side -- however Cloudflare on the GHL side may be blocking it as well.

Any way to connect to GHL via Oauth2 in this?
