Connection to a AC2729/10 failes with urlopen error [Errno 111] Connection refused>

[JoeKN2]

Hi,
I have new AC2729/10 device ([email protected] Firmware). The android app is able to connect to the device. It has the fix IP 192.168.178.74 (host has the IP 192.168.178.11)
I tried to connect but get an error:

I tried it with and without sudo.

Any explanation for this behavior?

You can try switching the protocol with either:

airctrl --ipaddr 192.168.178.74 --protocol coap

or

airctrl --ipaddr 192.168.178.74 --protocol plain_coap
