Here is the deal. Good diplomacy you have to back and forth. Make both feel like you want to support them if only they did X/Y. But what Germany did was not even trying to preserve the relationship. There is a balance there. Not allowing the Austrian to make war in the Balkans is pretty basic, and that's all that was needed. What was Austria gone do, not like they have other options.

German had all the cards and simply played them in a bad way.
