i work on Win10.
i tried to login into the avast ui but it comes up an errors, connection to login server @ Avast could not be established.
I have MVPS hosts in use, to prevent AD and else.
After investigation, i have found out the following: remove www.googletagmanager.com from the MVPS list and you can login.
see local DNS Cache :
using DNS Cache without MVPS entries in the Hosts File:
www.googletagmanager.com

Login does not work
but before login, try ipconfig /FLUSHDNS and - deactivate and reactivate your Networkinterface (or WLAN Interface).
(i have done this only with flushdns, and login does not work. after resetting the lan interface with on/off to activate, then it works)
then take login data to the AVAST UI and cklick to login, it will be work now.
hope, someone will be helped.
greetz !
