Link formatting in a wiki page

A developer is including some links in a wiki page for reference for our developers and our clients, and one of the links will not take on the link format (clickable, etc.). He's asking why and I don't find this in the docs. My guess is that it's one or more of these reasons? 

  • The link requires VPN access
  • The link has .local in it (
  • The link has a statement like this at the end: /define?grain=patient

If you can help me explain this to the user, thank you!
