(Google Drive) Your authentication token is invalid. Please try logging in again


I get this error consistently now and it’s persisted through the past couple of Insync versions.

When I click on the notification, it takes me to a Google login screen, but once I try to login, I get this error:

I can bypass this error by copying and pasting the original URL to an incognito window and logging in that way, but it doesn’t get rid of the “Your authentication token is invalid” error.

This seems to be an old issue that was supposedly addressed in a previous update but it’s come back for me over the past couple of months.

Hi @moeschl,

Indeed, this is being reported again, particularly by Google Drive users (the previous fix was for OneDrive).

Does the error above persist if you try logging in via alternative method?

Please also send your logs.db and out.txt files to support@insynchq.com so I can forward this to our engineers. Thank you!

I can confirm I see this on Mac, too. When I then click the pop-up to re-authenticate, InSync immediately pops up a new notification again saying “Your authentication token is invalid.” But if at this stage I quit InSync and re-start it things do seem to work as normal.

This has happened a few times over the past few weeks. I have not seen this happen on my Linux machine.

Thank you for the lead, @RobinJ1995. Let me forward this to our engineers to investigate the issue further.

Reviving this issue as it appears to be happening again. I’ve just sent an email to support@insynchq.com with my logs.db and out.txt files. Unfortunately the alternative method isn’t much help as that only seems to apply when you are adding an account. I tried using it but it said that the account was already present.
