Unable to establish connection

[KartikJoshiUK]

The remote server returned an error: (400) Bad Request. Got this error in visual studio. I got this error even though I am using the same code at the same network in the same machine and the server is working properly as its connects with postman and sanity.io-client easily. This is the whole error I got at line 278 in

\Plugins\Socket\Quobject\EngineIoClientDotNet\Client\Transports\PollingXHR.cs

Line was like this =>

using (WebResponse response = this.Xhr.GetResponse())

Full Error
