Code isn't working for auth page

[GetFractional]

I had this chatbot installed on Vercel initially not using the one click deployment, but it wasn't forked properly. I just recently deployed it by forking the original, and have all of the environment variables set up EXACTLY as before. I've been using it with no problem, and then out of nowhere, I started receiving this error message:

Clicking on the auth link takes me to the gated login wall, where I enter my code (the same one set in my environment variable and within the Settings), and it brings me right back to the chat screen. But when I type in a message or retry an old message, it just gives me the same error.

How do I fix this? Note that I'm using a custom endpoint for a proxy that gives me API access to GPT-4-32k and GPT-4, which is the reference to CattoGPT.

Any help with getting this resolved would be greatly appreciated.

Best,

Matt
