No valid orbit file found for 29-MAR-2021 01:20:11.000000

I am having difficulty retrieving the orbit information from the end of March to the beginning of June (2021). I have searched the POD manually and found orbit files which seem to do the trick.

I am unsure of how snap decides which file to use or why it cannot access the same dates.
I definitely have not read up on how this all comes together and would appreciate any guidance.
Thank you
