Auth/providers works in localhost but 404s in prod

[glyyynn]

I really don’t know what details to share here. I’m only trying to do a github auth with my next app (app router) and it will show the auth page for Github successfully in localhost while I have the callback url set to localhost. When I deploy to vercel and change the url to my domain, it 404s. I’ve checked my env variables a million times, and just created a new OAuth app, asked ChatGPT for debug steps and gone through everything I can ad nauseum. If anyone can suggest other troubleshooting steps I’d appreciate it. All auth routes just 404 even when I try to visit them directly, other routes work fine.
