What does that mean?
Can't find that in the code...

i am new here so not at all qualified. but for me this error occured when i misconfigured the mqtt credentials.
so this is related to mqtt things not being able to reach the mqtt broker, i think.
try url test.mosquitto.org:1883, this is a public test mqtt broker, to see if you can make a connection at all.
leave username and password blank for the test broker.
