Safari and duck duck go are no go for accessing this site
 

When I use my normal search engines to access PS, this site doesn’t exist. To write this, I’m using modzilla VPN. Regular modzilla works, but safari and duck duck go are a no go.

Any ideas?

Try clearing cookies and cache.

I can access it via Safari.

Also, if you navigate to the site using a bookmark (read, a link you have saved on your browser), these can sometimes fail.

Just navigate to the site by the home page URL https://www.professionalsoldiers.com/ and save this as your new bookmark.
