Hey there, @nikki! 
First of all, thanks for the reply and sorry for the vast delay in my reply.
And I know it has been a rough year for the Insync team, with all the 1.5 vs. 3 issues, and all. It was a rough year for me too. For everybody, I guess! 
The problem I was facing was referent to the same issues described, by myself and the others, on this thread above us…
For now, I ended up solving this problem when I migrated my file server service from my old Ubuntu 16 LTS to a NAS solution, which has a built-in GDrive file sync service app.
I’m catching up with the team’s official statement, and I’m glad to hear that “1.x users will be grandfathered”, about the headless interface. 
Thanks again, anyways!
