Subdomain stopped working overnight – wrong IP not resolving

It means that something on your end is interfering with the DNS resolution. It can be your company, your school, your ISP, your antivirus… But it’s not the hosting because it works for me. Our nameservers are responding the records correctly. DNS records for pop-grafika.xo.je from nslookup.io So you must contact whoever is making this block to get the problem resolved. As a workaround you can try changing your DNS resolvers to Google’s 8.8.8.8 or Cloudflare’s 1.1.1.1.
