Occasionally, I will be disconnected from a game and I will not be able to join/create games for awhile afterwards.
Does anyone know what this problem is/what I can do to fix it?

You get a "FTJ" issue a lot when you have been creating a lot of realm games without allowing time in between creating realm games. Simply select another one of your heroes/ heroines and you should be able to create another realm game, but try and make your realm games last longer if you are Xfering, MFing or running "Baal" realm games. GL man.

Its a joinbug, you cant make more than 20 games in 1 hour

There is nothing you can do to fix it.
Except for waiting 7 min.

The 2 guys above explained the reason why it happens

Try following this guide to remove "bnetcache" from your D2 folder, It helps alot with random disconnets & cannot create/join games
