Tplinkdns.com DDNS Service isn't working with 1.1.1.1

I can’t connect my website with 1.1.1.1. My website use tplinkdns.com DDNS Service(it bundled with tp-link router). My experiment(in Pictures) shows that if 1.1.1.1 queries tplinkdns.com, it will not respond. I’m use KT Corporation(In Korea) for ISP.

Neither does any other resolver. You need to fix your DNS setup.

tplinkdns.com is very broken and noncompliant.

I’d encourage you to switch to a better dynamic DNS platform if you can.
