🛠️ Diagnostic & Proxy Info

                Click "Test Server Connectivity" to run diagnostics.
            

Why timeout? Direct browser requests to 38.150.64.36:20003 are blocked by CORS policies or firewall. The EIMS server may not include Access-Control-Allow-Origin headers.

✅ Solution implemented: Using public CORS proxy (cors-anywhere.herokuapp.com) to relay the request. The proxy adds required headers.

Alternative: Deploy a tiny backend script (PHP/Node) on your own server that forwards the request without CORS restrictions.
