Version check .. MAC ..nothing more LOD US East/Euro

i am runnung Diablo 2 LOD on 2 macs (2 different CD Keys) with 10.14 installed. it runs fine and i still can play single player games etc…
but since a couple of days i cannot play Battlenet anymore
it stucks on “Version checking” and i can’t get further
at first it happens on the USA East Server, few days later on the Europe Server?
What is going on there?
