Tortoise.publish can hang forever

[brianmay]

Hello,

Under certain circumstances Tortoise.publish() can hang forever. Even specifying a timeout=10 value does not help.

The reproducible test case I (accidentally) found is when connecting to a MQTT server using Tortoise.Transport.SSL where the server it not configured to use SSL.

I would expect to get an error in this situation or a immediate return with no error (as QOS=0), not a indefinite hang.

Regards
