iotc.connect failed after internet reboot

[5MarsR]

hi,
so we had a power outage and i had a rapsberry pi 3 with the iotc librairy, in case of a power failure code will just restart after power is back on. when i used the librairie version 3.3 we never had any problem, but when I upgraded to version 3.5, after the reboot it seems the internet router was taking some time to restart, the previous version would still work if the power went router closed but with this new version I got this error and i am not sure if the problem was just the lack of internet that raised this error cause our whole system kept on rebooting and failing again.
