Then i added a page rule for 301 for this domain ohmymi.sg
makersblock isn’t resolving. Can you post a picture of your DNS page? I want to see which records are there. Can you also verify that the name servers at the bottom of that page are Grace and Jakub?
DNS name servers don’t appear to be properly set. Did you ever enable DNSSEC on this domain? See if your registrar has this option and that it’s turned off.
