We hit an unexpected error - Vercel Security Checkpoint - VPN

Every now and then (I haven’t measured the exact time, but it seems every 15-30 minutes), the T3 Chat UI shows the above error message. The “Reload App” button doesn’t do anything when clicked. Pressing F5 to refresh the browser shows the Vercel Security Checkpoint for a bit, then the T3 Chat UI works again.

This started last week or so, that’s also the first time I’ve seen the Vercel Security Checkpoint UI. The error seems to be related to that as well, given that the technical details are Vercel’s HTML document?!

I should note that this only happens when I access T3 Chat from my company’s network. That also causes other problems like LLM answers only appearing after they’ve been fully “typed out”. In the network tab, I can see a lot of “429 too many requests errors” for some requests like “api/server-version” and “api/status”, which could be related.
