Token authentication error for posting updates

[Jitendrudulacaraju]

I get this error:
The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel.

Code:
userName = loginView.TextBoxUserName.Text;
            password = loginView.TextBoxPassword.Text;

            catalogService.Url = @"http://Server/arcgis/rest/services";
           requiresToken = catalogService.RequiresTokens();
            if (!requiresToken)
            {
                tokenServiceUrl = catalogService.GetTokenServiceURL();
                tokenServiceUrl = @"https://Server/ArcGIS/tokens/gettoken.html";
                tokenCredentials = new TokenCredential(userName,password);
                TokenGenerator tokenGenerator = new TokenGenerator();
                token = TokenGenerator.GenerateToken(tokenServiceUrl, tokenCredentials);
            }
           
            Mapservice.MobileService.ServiceConnection.TokenCredential = new TokenCredential(userName, password);
            mapservice.MobileService.Url = "http://Server/ArcGIS/services/StormWaterMobile/MapServer" + "?" + token;
        }

It is really simple, not sure if a code snippet is really necessary.
What it does? See google:
