3 weeks ago @stefranco1983 Error 66 means that the server is disconnecting the socket (closed by peer), so it`s telling you that there is a problem with one of these:
- Client ID
- Credentials / Certificate
- Connection payload / flags
At first glance, I believe you need to set the hostname to the "server hostname", and you need to provide the client with the server X.509 certificate (provided by hivemq, probably found in your account somewhere). The hostname is the hostname that was used to sign the certificate, so if it does not match, you will not get to connect.
Using the test server, I get the same error 66 until I add a certificate... but since I don`t have an account, I do not have a valid certificate for this server, and it gets rejected with error -715050: Remote Host Identification has Failed. That suggests that all you need is to find your server certificate and pass it in with the correct hostname.
If you do not provide a certificate (Ready for SSL = False), then it tries a non-TLS connection. That might work for port 1883, but not port 8883...
This is where the connection happens:

Hi, sorry for my trivial question. I downloaded this library and it seems very interesting. I need to connect with a server that uses the SSL protocol (hivemq.cloud). No certificate is currently required on the server. To log in I only use my username and password. When I start the program, "Connection accepted" appears but there is error 66. The software hangs on "Connect to Server.vi".
Could you help me?
PS: Setting url and credentials to an old TCP server (cloudmqtt.com) works fine.
Thanks for the support.
