Error when using [Server Sent Events (Deprecated) / HTTP Streamable] in MCP module

[Randolph_Nunez]

Hi,
I keep getting the following error when using the [Server Sent Events (Deprecated) / HTTP Streamable] option in the MCP module:

Could not connect to your MCP server 

Can anyone help me understand what’s causing this and how to fix it?
I’m not sure if I should be using “Server Sent Events (Deprecated)” or “HTTP Streamable,” or if there’s a configuration I’m missing.

Thanks in advance!

Use the Streamable HTTP protocol and recreate the mcp server and update the mcp server URL. This helped me fix the error.
