Error 522 when client using FPT Internet service

Dear Cloudflare support team,

My website using Cloudflare SSL service.
Domain: ipeoplex.com
My server location in Hanoi / VietNam.

Now all client using FPT Internet service when connect to website ipeoplex.com has Error 522 (Connection timeout) all case using http and https protocols.
I login Cloudflare and change DNS from [DNS and HTTP proxy] to [DNS only] then this client can connect to mysite using http protocol.
I think transmision has problem between CloundFlare Hanoi and FPT Internet Service provider.
Please help me fix it.

Thanks for your support
