I’m getting this error, I have already browsed the topics, I found similar issues, but none of them solved my problem, I also have cloud flare and I’m using cloudflare server names:

I even try to switch back to the hosting server names:

ns1.byet.org
ns2.byet.org
ns3.byet.org
ns4.byet.org
ns5.byet.org

and also attempted to remove 3,4 and 5. but nothing works.

This is the error I’m getting:

This site can’t be reached estudioea.net’s server IP address could not be found.
Search Google for estudiosa net
ERR_NAME_NOT_RESOLVED

Used VPNs and still can’t access the site, also flushed cache and DNS. nothing works.
Please help !. this is very distressing .

site:estudioea.net

thanks for your time.

Loading and showing empty directory listing for me, wait until DNS propagation will get your domain working for you.

I just checked your domain, and it’s no longer working for me. Your domain is currently pointing to Go Daddy, not to us. Please change your nameservers back, or I can guarantee you your InfinityFree account is not going to work.

Also, please don’t forget to add the domain name to a hosting account. If the domain name is not assigned to an account, it will not work either.

ok. Thanks.
I will start everything from scratch on a new account.

my name servers in the domain are back to

ns1.byet.org
ns2.byet.org

DNS and cache are flushed. but now I can’t even start from scratch.

Now I get another error:
