Error message error - connection error

I'm on a Mac computer, and when I tried to connect just now I got an error message, but the connection problem is not the error i'm reporting.

The error message has a hyperlink to "https://support.riotgames.com/hc/en-us/articles/201751984-Connection-Failure-Error-", which is not an actual page. So, kind of just worthless. Please update the error message, riot.
