Picnic integration broken, fails to find 'address'

[RMHogervorst]

The problem

Picnic integration is failing for me, for a while now. So I tried to remove my current credentials and add again. But during log in I get an 'invalid authentication' error, but it seems that the problem is somewhere else.

Included is a part of debug logs.

restarting home assistant actually fixed the problem, I could install and log in again.
