SSL.ZeroReturnError is raised when the connection has been closed cleanly, and no more data will be received. This behavior indicates that the connection is no longer usable and thus can be considered a type of connection error. Therefore, it is appropriate to raise a ConnectionError when encountering SSL.ZeroReturnError.

SSL.Contextwithin the MQTT client.tls_set_contextmethod to facilitate compatibility with bothssl.SSLContextandSSL.Context.Purpose:
The introduction of PyOpenSSL support serves to broaden the library's compatibility spectrum, particularly for scenarios involving PKCS#11 integration. This enhancement enhances the versatility and usability of the
paho.mqtt.pythonlibrary.Related Issue:
