While try to re-align my Stripe account with Hashnode sponsors page, suddenly Hashnode displays this error message.

I am not the owner, it tries to re-route the web page to : vercel.com/docs/error/application/ROUTER_EX.., when I clicked learn how to fix the error, it only shows a Vercel page with a message 404 Page Not Found

One of the suggestion given by one of the user of Hashnode to fix this problem.

Unfortunately, the chatbox only displays black and white.

Please do let me know how to fix this problem. All kinds of ideas are welcome.
