Why is it when game full or game already exist etc…game client needs to be restarted or wait a 1-2min b4 you can try to make or join a game again ?
Restarting can put you in a login queue so you don’t want to do that.
The Global Database for D2R is not handling the volume of data well which is why the game was down totally for 4-5 hours a day from Oct 9th - 14th. The rate limiting of game creation is temporary until they get the Database fixed, which is not easy to do on a live released game.

What we are doing about it:
Rate limiting: We are limiting the number of operations to the database around creating and joining games, and we know this is being felt by a lot of you. For example, for those of you doing Pindleskin runs, you’ll be in and out of a game and creating a new one within 20 seconds. In this case, you will be rate limited at a point. When this occurs, the error message will say there is an issue communicating with game servers: this is not an indicator that game servers are down in this particular instance, it just means you have been rate limited to reduce load temporarily on the database, in the interest of keeping the game running. We can assure you this is just mitigation for now–we do not see this as a long-term fix.
