Solace Community is getting a facelift!

On March 3rd we will be starting the process of migrating Solace Community to a new platform. As a result, Solace Community will go in to a temporary read-only state. You will still be able to come onto Solace Community and search through posts to find answers, but you won't be able to ask questions, post comments, or react in any way.

We hope to have the migration complete by Wednesday March 5th (or sooner), so please keep an eye out!

    Hi @dndoanh
    I believe the tutorial didn't include that we need to have a trust store to connect to secured ports. I'm guessing the error is because of something like this: failed to load trust store: unspecified property 'SESSION_SSL_TRUST_STORE_DIR'
    probably something like this:

    If you don't need secured SMF, you can enable plain text ports during the creation of the Solace Cloud brokers like below:

    Hmm I am not familiar with the error. But no harm to double check the ports and properties are all correct. I remember seeing something about version not correct when I used the wrong port once :)

    @dndoanh I think @arih is on to something. Could you check your host parameters are using port 55003, and NOT 55555 (the default)?

    @Poornima @marc I haven't resolved this issue yet, it's only working with plain text port 55003, secured port not working

    @Poornima, I made a mistake in my reply. The SSL port is 55443, NOT 55003 as I had earlier, which is the compressed port.

    Hello,

    I too stumbled on this issue and got the resolved with a suggestion provided by @alamkhan786 . Hoping this well help someone in the future

    1st option and disable complete chain verification

     // Create session properties

          SessionProperties sessionProps = new SessionProperties()

          {

            Host = host,

            VPNName = VPNName,

            UserName = UserName,

            Password = Password,

            ReconnectRetries = DefaultReconnectRetries,

            SSLValidateCertificate = false

          };

    2nd Option - Load the store which has the Trusted CA public certificate

          X509CertificateCollection certificatesCollection = new X509CertificateCollection();

          foreach (StoreLocation storeLocation in (StoreLocation[])Enum.GetValues(typeof(StoreLocation)))

          {

            foreach (StoreName storeName in (StoreName[]) Enum.GetValues(typeof(StoreName)))

            {

              X509Store store = new X509Store(storeName, storeLocation);

              try

              {

                store.Open(OpenFlags.OpenExistingOnly);

                foreach (X509Certificate certificate in store.Certificates)

                {

                  certificatesCollection.Add(certificate);

                }

               

              }

              catch (CryptographicException)

              {

                Console.WriteLine("No      {0}, {1}",  store.Name, store.Location);

              }

            }

            Console.WriteLine();

          }


    Use it during the setup of SessionProperties

       SessionProperties sessionProps = new SessionProperties()

          {

            Host = host,

            VPNName = VPNName,

            UserName = UserName,

            Password = Password,

            ReconnectRetries = DefaultReconnectRetries,

            SSLTrustStore= certificatesCollection 

          };


    Hope it will help the community.

    Best Regards,

    Franklin
