Hi there,
today we changed the authoritative servers of the domain probankleasing.gr (we moved it from a greek provider DNS servers to the Akamai Edge DNS service). All public DNS servers that I have tested, like Google’s 8.8.8.8 and many others, can resolve to the new auth servers and complete the resolution normally, except for 1.1.1.1 and 1.0.0.1. The changes have been implemented at least 1 hour ago. Here are some dig outputs (from your DNS troubleshooting guide):
