Gitea with Github OAuth throws error 500

[yusf]

When trying to sign in to Gitea by means of the Github OAuth authorization scheme, Gitea throws error 500. This is what logs in the back:

Feb 06 13:59:53 2019/02/06 13:59:53 [...routers/user/auth.go:548 handleOAuth2SignIn()] [E] UserSignIn: Post https://github.com/login/oauth/access_token: dial tcp: lookup github.com on 127.0.0.11:53: read udp 127.0.0.1:47621->127.0.0.11:53: i/o timeout

Up until the last or last few updates, this has worked flawlessly. Is the error Gitea's or Github's?

@yusf Can you check if unbound is running ? It's in system -> services.

[yusf]

It was not! After clicking its restart button the service came to life and Github OAuth works. Thanks! The box was freshly rebooted however, so how can I make sure unbound doesn't go down?

@yusf This should be automatic but unbound goes down if the disk space is full. There is no workaround for this since this is a bug in the upstream project and will get fixed at some point.
