Chat Pages Can't Be Found From Links

In my Nav Bar I have links going to each of the Group Chat Rooms, but I keep getting "Oops! That page can't be found" when I click on the link from the Nav Bar.

Now I have gone into, for example, the forum for Women Only. I click on "Group Chat" and the URL takes me to

I go into my menus and check the URL for the custom link for Women Only chat and it is identical to the one above.

Why am I getting "Page not found" from my Navigation links?

The Forum links work fine. It's just the chat links.
