SSL 'SSL-client' cannot read, sslErr = 5 in python client

Shijo

Not able to connect to the solace broker using the python client library.

Below mentioned how i connected:

SOLACE_BROKER_PROPERTIES = {
    "solace.messaging.client.name": "test-client",
    "solace.messaging.transport.host": "tcps://mr-test.messaging.solace.cloud:55443",
    "solace.messaging.service.vpn-name": "com-test"),
    "solace.messaging.authentication.oauth2.issuer-identifier":
        "auth issuer url",
    "solace.messaging.tls.cert-validated": False,
    "solace.messaging.tls.cert-validated-date": False,
}

token = OAuthClient().get_token()
authentication_strategy = OAuth2.of(token, None,
                                    properties[authentication_properties.SCHEME_OAUTH2_ISSUER_IDENTIFIER])
self.messaging_service = MessagingServiceClientBuilder().from_properties(configuration=properties).\
    with_authentication_strategy(authentication_strategy=authentication_strategy).\
    build()
self.messaging_service.connect()

It throwing an error like this:

Ignore this,

I thought this issue was because of my python package versions since I tried to upgrade some of the packages(eg: PyOpenSSL)

This is a kind of cache/network related. Issue got resolved once i restarted everything.

Thanks
