HTTP 401 issue using own OAuth2 client

[auriusbendikas]

I am using own Oauth2 client as documented in "Different OAuth2 client to workaround over quota and google approval issues". However it suddenly stopped working. I reviewed and recreated all credentials but it only works the first time when I execute grive -a --id <client_id> --secret <client_secret>. All other invocation of grive gives this error:

$ grive
Failed to refresh auth token: HTTP 401, body:

The fact that it works fine the first time points to an regresion in the grive code related to execution of grive after credential configuration.

In 2019 I used instruction and all work fine on other laptop , and in 2022 I am try to build from sources and install from repo Xubuntu 20.04 LTS and after grive -a and enter code got this:
