arduino uno + wifishield cannot connect bluemix using token - wifi

Question

I have arduino uno + wifishield and if fails to connect to Bluemix. It gives this error:
"Closed connection from 194.228.11.222. The operation is not authorized."
Any idea why the connection gets kicked out? What operation is not authorized?
Thanks for any idea ;)

It might be the case your organizations is configured to block non-secure connections (since you are using port 1883). Check the step 5 on this recipe

I noticed this error in the log: The topic is not valid: Topic="lwt" ClientID="d:6735ra:hlinoponie:petasek" Reason="The topic does not match an allowed rule".
I didn't see that topic listed in your code, but you may want to check to see how that may be getting set as topic.
