Back to login in-game

hello,

since yesterday I’ve experienced quite as few “back to login page” issues in game.
It seems that I lose connection to server and sent back to IN GAME login (battlenet is still fine and logged in)
if I’m fast enough I can type my login/password and rejoin, but very often at the beginning of the game it takes more than 10sec to get the login page and log back.
My wired connection is still up and shows no sign of disconnection.

Result: I’ve lost SR and I’ve been banned for 10mn yesterday and 30mn today.

This is very annoying.

I have 100Mb FTTH connection which is very stable.

EDIT:
and it just happenned again., twice in the same game in the first 10sec… now I get a 2h ban.

edit2: and 7 games at -75% XP in QP since it happens in QP too.

WTF

edit 3: conputer restarted, Firewall restarted, router restarted… still the same
