What happened?

I tried to set ipv6 link-local address as use_address and seems faced a bug. Every time Isee the following:

after this error the device log is not being connected anymore, but the device itself works well.
if I close log window and press log button -- it get connected.

How to reproduce

it can be reproduced with any device if set use_address to ipv6 link-local, as follows:

wifi: ssid: !secret wifi1_ssid password: !secret wifi1_password use_address: fe80::aa46:74ff:fe40:7bf4%bond0

Expected behavior

I guess it should be able to properly reconnect to the device after flashing
