@skkpnlq7t4g @Hah7qui I had the same error message on a self hosted server. As it turned out, it was the API key restriction settings on Google that rejected my server.

If you also have key restrictions, try create a new key without any restriction and see if it works, and then add some restrictions back while it works.

Thanks for your replay. The key has no restrictions:

@loganrockmore @NeverBehave @Sea-n @DIYgod @mengx8 @HenryQW any idea for this issue?

In self-hosted environments YouTube route is still not working out of the box. Maybe just a step in the doc is missing. https://github.com/DIYgod/RSSHub/blob/master/docs/en/install/README.md#route-specific-configurations
