Identify where the connection stops.
Check the endpoint first, then authentication, permissions and the result reported by your client.
The client cannot connect
- Compare the configured URL with the endpoint supplied for your workspace.
- Check connectivity from the machine or container that runs the MCP client.
- Inspect the client's server output for a timeout, network error or unsupported transport.
- Keep certificate verification enabled; resolve the certificate or hostname issue before retrying.

| Empty resource list | The selected workspace, environment and available resource scope. |
| Unknown method or tool | The capabilities actually discovered by your client. |
