The logs of real expired access token of cloud2cloud-gateway are below:

The error message rpc error: code = Unauthenticated desc = invalid token: could not parse token: token is expired of unexpired access token is different from the result of expired access token.

What is problem of rpc call ?

It seems to be solved in plgd/hub latest version so I will close this issue now.
