This is the screenshot of errors. However, I only registered this domain name but don’t host it on any other platform. I don’t know why it is judged as hosting on other accounts.
Hi and welcome to the forum! I had the time to dig the DNS records for your domain on our nameservers and it seems like it’s still hosted on MyOwnFreeHost, so you might need to contact iFastNet to remove it from there before adding it on your hosting account here, by either changing the nameservers to ours or using a CNAME record for validation.
