Authentication Source - Access token not working


I setup Hydra as an Authentication Source to issue access token.
But when I use this access token with Gittea API, it message 401 Unauthorized
The problem is I do not see any call from Gitea to Authentication Source (Hydra)

Anybody could help me explain why? or how to correct setup?

BTW, I try to use Hydra as OAuth2 provider and want to integrate with Gitea
