How to use OAuth passthrough authentication?

[SergueiEK]

Hello

I have configured Infinity to send requests to the REST API on remote host using OAuth passthrough mode. I have logged to Grafana using Generic OAuth authentication with the same credentials that are used by the remote REST service. But an attempt to read anything from the remote service results in 401 Unauthorised error.

Here is the output from the log file (server, user name and e-mail address are censored, but they are all correct)

Am I doing something wrong?

I'm using Grafana 11.5.2

Thank you
