See the manual for more info about time steps.

In this case with this maximum time step (2s) it is beyond the end time of that step.

So I would suggest to use something like 0.25 sec for initial 0.1 sec for min, and 0.5 s as max.

Also the time step depends what is the highest freq. in your system and can thus be taken as dt = 1/(freq_max) * (0.1)
(this is just a rough guideline for dt so we might need to sue smaller than that if we have lost of damping, contacts, fats load variations, etc)
All the best
