I have been working my way through the App Router course/tutorial that I found on the nextjs.org/learn page. Everything was going well for a couple days, but just today when I tried to get back into it, I'm met with a "Access Required" vercel page. I'm extremely confused by this sudden interruption and the lack of clarity as to the cause. I'm logged into vercel with my github and I can use vercel as normal, able to access all my projects and what not. But I quite literally cannot access the nextjs site at all, including the nextjs docs or the App Router course I previously mentioned. Any help is appreciated.
