embedded address won't work

Site URL: https://cat-harpsichord-8zm4.squarespace.com/news

I tried to embed this address into my site with the embed block, but it won't work. It worked in wix, but not on squarespace. I wrote the publication to if I needed to do something differently as far as the link is concerned, and they said it was something on the squarespace end..  https://buckrail.com/holding-space-is-what-makes-niki-sue-mueller-the-best/ Is there something I am missing that I need to do? The website page  I'm trying to embed it in is https://cat-harpsichord-8zm4.squarespace.com/news  password: leidysam   Thanks!

The url requires a password to see content, it can't embed needing that. 

Ah, ok. Just to make sure I know what your'e saying.. the squarespace website is password protected and that's why it isn't working? I think I read something about that.. or the actual link I'm trying to embed needs a password..
