Gmail_API: Invalid grant. Please reconnect your Gmail account Even if after reconnecting account

[Osebest]

I am getting Invalid grant when I send a request from my React app.
I made some research, and I saw I should reconnect my account.

I reconnected my account and when I click on "Update Service" I get the response below

Although I still get the test email on my gmail account, when I test on the React app, I keep getting the Invalid grant error.

Please try to remove the service and add a new one. You can use the same service ID.
Let me know if it helps.

Yeah this worked.
I deleted the service and added a new one using the same service ID, worked fine.
Thank you.
