Chat.openai.com sending FIN-ACK

Hi there, being that I cant get to chat[.]openai[.]com I am starting this here.

I can get to all other openai[.]com sites but if I go to chat[.]openai[.]com, I am get FIN-ACK. communication completes three way handshake, client hello is ACK’ed by server and then FIN right after from server. I have confirmed this in wireshark.

What could be reason for this? This was working until yesterday. What changed? Nothing changed on my side. I have tried this on two computer on Brave and Chrome browsers. This is what my browser result looks like.
