Can't connect to vacuum anymore

[SebRut]

Since 2-3 weeks I'm not able to connect to the vacuum anymore, neither by using homeassistant or python-miio manually from different devices. I am able to ping the device and control it using the MiHome app but local request fail with the following.

Got exception while fetching the state: No response from the device
Got exception while fetching the state: Unable to discover the device 192.168.0.183

Running mirobo --ip 192.168.0.183 --token [TOKEN] -dd info lead to the following log:

When the discovery is still working, the timeouts are commonly caused by incorrect token. Could it be that the vacuum has reseted itself and by doing so, changed the token?

That's it! Thank you.
