There appears to be a problem with abuse of rclone's client ID which Google is cracking down on.
I'm receiving 50 emails an hour from users of sites such as gdtot, mkvcinemas and katmoviehd about this. These sites aren't using rclone, just it's credentials as far as I can make out.
Unfortunately this is affecting genuine rclone users too.
Hi, thanks for responding. Can you give me some detail as to how I can accomplish that? So far I only know how to enable API and create credentials for the account I want to use with rclone, but not for a different account.
I had the same error leaving things blank like I used to do.
I followed the guide here Google drive
Everything works fine, authorised and all working. So I guess you need to re-check your setup. If your using a previously added OAuth then dont. Create a new app, new OAuth ID and Secret and you should be good to go.
