D2 LOD - Battle.net not responding, please try again later

Guys, after 6 years I decided to go back to playing diablo 2 LOD, I logged into my old Blizzard account, recovered my old cd keys, downloaded the games and the moment I tried to enter battle.net, I got the message: Battle. net its not responding please try again later. I researched a lot and saw that many people have this problem and no effective solution. I would like qualified help to solve this problem for so many players. What’s up, blizzard? solve this or return my money!
