Gitea Oauth2 app not able to login to drone

I am able to setup my gitea instance and able to login and create the repos on my instance.

When I create oauth app I have setup redirect url of my drone server, but When I login to my drone instance I dont get any gitea oauth prompt to access my repos from my gitea instance.

Gitea: http://xxxx:3000
Drone : http://xxxx:100

I have tried using gitea and drone docker compose on both same machine and different machine.

I am facing same issue.

Please help!
