SAP Business One Service Layer:The remote server returned an error: (502) Bad Gateway.
Hi,
I am trying to login to Service layer in c# url using format
{"CompanyDB": "US506", "UserName": "manager", "Password": "1234"}
I am constantly getting the following error "The remote server returned an error: (502) Bad Gateway."
Below is the code I am using:
private static bool RemoteSSLTLSCertificateValidate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors ssl)
{
//accept
return true;
}
static void Interact(string url, string method, string body = "")
{
var httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
httpWebRequest.KeepAlive = true;
httpWebRequest.Accept = "application/json;odata=minimalmetadata";
httpWebRequest.AllowAutoRedirect = true;
httpWebRequest.ContentType = "application/json;odata=minimalmetadata;charset=utf8";
httpWebRequest.Headers.Add("Prefer", "odata.maxpagesize=10");
httpWebRequest.Method = method.ToUpper();
ServicePointManager.ServerCertificateValidationCallback += RemoteSSLTLSCertificateValidate;
if (!string.IsNullOrEmpty(body))
{
using (var stream = httpWebRequest.GetRequestStream())
{
StreamWriter writer = new StreamWriter(stream);
writer.Write(body);
writer.Dispose();
}
}
try
{
using (var response = httpWebRequest.GetResponse())
{
var reader = new StreamReader(response.GetResponseStream());
var data = reader.ReadToEnd();
}
}
catch (Exception ex)
{
}
}
Found that the web exception in details is
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>502 Proxy Error</title>
</head><body>
<h1>Proxy Error</h1>

Reason: <strong>Error reading from remote server</strong></p></p>
</body></html>
Please help. Am unable to get my head around what I am doing wrong.
Thanks and Regards,
