Just another helpful tip.
If you experience on all your characters in your account can't create games or join existing games.
Immediately STOP joining and creating games, the more you try the longer they IP ban you and
log off D2 right away. So once you experience this, just please log of D2 and just chill out because your characters are tagged in their server system and the more you try to join/create games the longer they ban you. Most of the time, it's you joining/creating games too fast and that is why they tagged your character then if you continue they will tag your account CD key to their system for the 2-4week IP ban thinking you were botting or using 3rd party programs.
They do a daily server reset everyday 12pm EST. Just chill and try to do it once every couple hours or 12hrs or next day 12pm EST and you should be good and not get the 2week-4week ban.
Hope this is helpful to everyone to the D2 community
