HiveMQ Cloud fully supports SSL-encrypted TCP connections on port 8883. To ensure a seamless connection, kindly verify that your client is configured to utilize the correct port.

In order to establish a secure and trusted communication channel between your client and the HiveMQ Cloud broker, it is essential for your client to recognize the Certificate Authority (CA) associated with the broker. To facilitate this, you might need to include the broker's CA file within the trusted certificates section of your client's configuration.

For your convenience, you can easily obtain the broker CA file from the following link: https://letsencrypt.org/certs/isrgrootx1.pem. Upon downloading, the file will be named "isrgrootx1.pem." This file can then be utilized as the "Server Certificate" within your configuration.

The client should support and have enabled the TLS-SNI extension (This extension allowed the client to indicate the hostname it was attempting to connect to during the initial TLS handshake.)
