got the same issue yesterday... or the day before that, still is not resolved

tried uninstalling the extension, close the browser, then use the re-install button in the avast program. Still fails to handshake/connect
EDIT:
FixedFor me at least, I uninstalled the extension, restarted my computer, added the extension back on via the avast app.
and it works now.
