Hi, about 2/3 weeks ago, I entered the DNS of Cloudflare on my domain and everything was fine, I wanted to try the mode “They are attacking me” (later I deactivated it and then removed when it gave me an error ) and from that moment on, the site, with the cloduflare dns, started to give “problems”.
Change the dns and always insert dns cloudflare:
gives me this error here: "The entered NameServers are not valid, you can check them through the page http://dns-check.nic.it (also changing dns but always leaving dns cloudflare).
The dns are working, because sending packets (pinging), they answer me.
If instead I leave the factory dns is fine.
I would like to insert the cloudflare dns but I would like to fix this error here.
I think that since I put the configuration “I’m under attack”, the dns has blocked some door or something, and now I can not unlock it. I would like to know if possible, you can solve the problem or enter the dns requested by me. Thank you so much and sorry for disturbing you.
Sorry for my bad English.
