Register devices in cloud app

[Daniel]

Yes you need outgoing port 1883 to be opened.  Usually all outgoing ports are open and only incoming are blocked.

I have now checked with it, and they tell me there is no ports that are closed. I have checked the error log again. I cleared the log last time. And since then there are no more errors. 
Still the same that the mosaic is not updating. Everything is there, but nothing is updating. 

Any more ideas that i can try?

Send me your cloud user to PM, I will check on cloud if everything is ok there.
