Why are my current simulations taken longer than before (went from 1-2 weeks to 1-2 months)

GROMACS version:
GROMACS modification: Yes/No
Here post your question

GROMACS: gmx rms, version 2020.1-Ubuntu-2020.1-1

How come when I have run previous MD simulations they have only taken a week maybe 2. The current run I have going is saying 2 months? why?

Is there something I need to correct? I have not changed anything in my MDP files from previous runs, could it be my internet?

Thanks in advance,

Heather
