Losing connection between Integration Service and Google Sheet

I am having problems with Integration Service and Google Sheets.
I have tons of activity that needs to be done using Google Sheets (around 20 automation).
The thing is that sometimes there is a disconnection between Google Sheets and Integration Service.

What seems to be causing this issue?
Is that the best way of connecting UiPath and Google Sheet / Google Documents?

You will need to check the connections in Integration Services and fix them.
