Interpolation Error in HFSS. Anyone have a solution for it?

Hello

I am using HFSS for my PCB trace SI simulation. In my sweeps, the solver getting struck in one point at a particular interpolation error thinking that in that frequency convergence will occur. for example at freq 2.5 GHz where the interpolation error is 33%, the solver is thinking the convergence will occur at that frequency range making successive simulation in frequencies nearby to that.

Anyone faced this problem and have a solution please reply back.

Thanks
