OK but the notice at top of the forum did not speak about the existing my.avast.com site, but the NEW version in beta-test.
The normal My.avast.com should continue working.
Visibly Avast is playing with certificates, and has created new ones that do not validate with all its old and new servers.

Both the website and the application are affected by weird errors. And these are not beta-tests of the future new portal

Note, Eddy, I don’t know who you are and I cannot check your real status, the server says I cannot display your public profile. It’s possible that you are one of the attackers connected on the forum and impersonating someone.
