Request failed due to auth token expired: 401

[kp3393]

Hello team,
I have been using Grive2 to sync my data on the server with my google drive. I created my own Oauth2 credentials as per the documentation and was able to download my google drive to the current directory.
However, when trying to upload the data from the server to the google directory, the sync usually stops after an hour, and I have to restart the sync again. The files I transfer are relatively huge (almost 300-400 GB).

This is the recurring error:
