It maybe related to not being logged out after switching networks (see steps to reproduce). I'm not sure if this is expected now.

@mandrigin or @rasom, could you take it?

All works fine on previous nightly 248e60. So, there are only couple of new commits in which the bug was introduced:

[asemiankevich]

@alwx please take a look. Also #6378 could be related too.

UPD: here is the API commit that broke it #6341
