Devices lost connection to MyQttHub


Service appears to have stopped working today at around 11/01/23 04:45 GMT - all my devices are unable to send messages.


Hello Keith.

Just confirm everything is working as expected and no failure has been reported.

We are handling this directly at (we have just replied about this)

Best Regards,


Hi Claudio,
I have had over two hundred devices connected for many months which have all stopped sending via MyQttHub - a similar number sending via another service are all working OK.
There does appear to be a problem.


Just to confirm that the issue is now resolved. The public IP address of our 4g SIM network (1nce) had been blocked by MyQttHub - once unblocked the devices were able to communicate again.
