Tags '*'); res.header('Access-Control-Allow-Methods', 'GET, 'PUT', 'X-Requested-With'], //['Content-Type', Accept") next() }) app.listen(port) i can't make a simple GET Request on client side. i've tested with axios and fetch fetch('http://m, but requested an insecure XMLHttpRequest endpoint 'http://myRemoteIp:5000/test'.
