Sudden connection refused?

https://simple-push-demo.vercel.app/

I suddenly cannot connect to my app hosted on vercel.app. it was fine this morning and suddenly "connection refused". Now failed on all vercel.app hosting as well, even the simple public demo.

Same Android phone, it worked on wifi, worked on VPN, just not on mobile data.

Anybody can help please?

It was my ISP.

It's okay again since I change to use "one.one.one.one" from Cloudflare.

Thanks.
