League Keeps Giving Me a PvP Error When I Try and Sign In

It's ONLY the first time when I attempt to sign in that it gives me this error message. It basically says something along the lines of "Connection Failure: Unable to connect to the PVP.net server issue". Once I click for the error message to go away, it simply closes the entire client and I then click on the icon again to load it back up again. Once I try to login a second time, then the game works, doesn't give me the error, and logins me into the client normally.

Very odd...anyone else been having this issue?
