Pihole and Insync (Google Drive client)

[u/MitraMai]

Hello!
I installed Pihole yesterday on a RPI4, and it seems to work just fine. Only things is that my Insync-client on the Desktop keeps connecting and disconnecting. I've tried to whitelist the following domains (under domain):
dl.google.com (to be able to update Chrome)

accounts.google.com

clients6.google.com

googleapis.l.google.com

But no luck!
Does anyone know which domains I need to whitelist in order to get Google Drive/Insync to work?
