Login difficulty on mobile

When using the site on my smart phone (LG2 from sprint) previously i had no issues.

Now (past 2 days) when i try to log onto the boards i get "user name and password invalid" As you can see by me posting here, (from my PC) i know my username and password. Also my in game account uses the same username / password i have always used with this game, so i am not sure why i am having difficulty logging onto the boards on my phone when in the past i was able to.
