Snap-through model convergence issue

Hi all, 

I am having issues with the convergence of a model. The error reads: time increment is less than minimum specified. This is what I tried so far: 

Refining the mesh.

increasing IA(increment attempt)-steps module-other-General Solution Controls-Edit-Step-1-continue--specify-Time Incrementation-more-IA=30

Any ideas of what else I can try?

Thanks!!
