Email links are not yet pinned to a trusted host,

Hello,

On the admin page, I’m getting the error message “Email links are not yet bound to a trusted host.” When I follow the instructions at https://learn.getgrav.org/20/security/trusted-host#the-fix (Option 1), my website no longer displays correctly. Unfortunately, as a new user, I can’t upload any images yet. Maybe it’ll work in my next post.

What am I doing wrong?

Here's the link to the screenshots -> https://abigailsh.privatedns.org/index.php/s/nnZbAfNkZkdHmAn
