Redirect to defaultwebpage.cgi

Hi,

I have just migrated my WordPress site a new web host.

My website is https://thefinance.sg and I’m redirected to https://thefinance.sg/cgi-sys/defaultwebpage.cgi

However, I am able to access my site if I put in a dot ‘.’ at the end. https://thefinance.sg.

In my old web host, I was using a sub domain but not anymore in my new host. I suspect that could be the problem or maybe a DNS issue? Any help is appreciated.

Thanks.
