Address not available when adding 169.254.170.172 to multicast group, it is expected to happen on some systems

When test connect to a robot I get this messages:

C:\alphamini\test>python test_connect.py
start scanning...

Well, I solved this in two ways, the first time I restarted my computer, in my case I use Windows 10, after restarting I managed to connect to the robot.

The second time it was necessary to restart the robot, after restarting it I was able to connect to it.

I don't know if it is related to zeroconf as mentioned in another issue.
