Error 522 When Connecting To My Website With "Türk Telekom ISP" Automatic DNS

Hello to everyone,

“Turk Telekom ISP” does not connect to my website with automatic DNS. It gives error 522.

1.1.1.1 is connecting.
Vodafone connects with automatic DNS.
I checked with ping.pe, other ISPs are connecting.

Only Türk Telekom does not connect and this means; Türk Telekom users using automatic DNS will not be able to connect to my website!

However, I checked, sites using different cloudflare NS addresses than mine can be connected with automatic Türk Telekom DNS.

How can I overcome this problem?

Thanks in advance for your support.
