Diego I understand that you are experiencing an issue with your website's name servers being automatically changed back to your registrar/host, despite your efforts to point them towards Ezoic. I recommend that you speak with your registrar/host to investigate what might be causing this.
It's possible that your registrar/host has some automated processes in place that are reverting your name server changes. Alternatively, there could be some security settings or restrictions on your account that are preventing the changes from sticking.
In any case, your registrar/host will be better equipped to diagnose and resolve this issue for you. They will likely need to review your account settings and logs to determine what is causing the name server changes to be reverted.
I hope this helps, and please let me know if there is anything else I can do to assist you with this issue.
