When Austria refused to honour the Russian alliance, instead declaring neutrality, and pinning down large Russian armies along the Danube, it clearly estranged itself from the Russian Empire. Yet, it doesn't seemed to have gained any consideration from France or Britain for this position.

How/why was Austria left diplomatically isolated, instead of forming a new alliance with France or Britain?
