Manuel Neuer looks set to go to the World Cup, but Germany's goalkeeper was unable to prevent his team crashing 2-1 to Austria on his comeback.
Neuer has proven his fitness after eight months sidelined by a fractured foot in timely fashion, with four names to be cut ahead of Germany naming their final 23-man World Cup squad on Monday.
But the 'keeper was powerless to stop second-half goals by Martin Hinteregger and Alessandro Schoepf after Mesut Ozil gave the Germans an early lead.
The result is a big concern for Germany head coach Joachim Loew with the World Cup to kick off in less than a fortnight.
The world champions are now winless in their last five games since suffering back-to-back defeats after losing 1-0 to Brazil in Berlin last March.
"It was a good comeback from Manuel after so long out," Loew told broadcaster ZDF.
"The defeat is annoying, we did well in the first half, but we lost a lot of ball in the second half and made life hard for ourselves.
"A lot of things were bad today."
