.NET SDK Agent - https (wss) configuration failed

[AlessandroN]

Hi everybody,

I'm trying to configure my .NET Agent to communicate to Thingworx over https (wss), but on the "start" method it gives me back this error.

com.thingworx.communications.client.TwApiWrapper Error: 0 : [Error] Error intializing SSL connection

Server:

The configuration on this client is the following:

            serverCertFileInfo.FilePath = ConfigurationManager.AppSettings["ServerCertificateFilePath"].ToString();
            serverCertFileInfo.CertType = 0; // '0' for axTLS
            config.ServerCertFileInfo = serverCertFileInfo;
           
            config.AllowSelfSignedCertificates = Boolean.Parse(ConfigurationManager.AppSettings["AllowSelfSignedCertificates"].ToString());
            // non verifica il certificato del server
            config.DisableCertValidation = Boolean.Parse(ConfigurationManager.AppSettings["DisableCertValidation"].ToString());
