Password reset not working

Recently tried to log into account and was unable to login using my normal username/password. I havent changed anything and am 100% confident that I am using the correct password (just logged in less than 2 days ago). After a few failed attempts I clicked the link to reset password and after resetting it I am still unable to login on the client. I can log in in the web browser on leagueoflegends.com but I still get an error stating my password/username is incorrect on the client. Is this some sort of bug? Is it a server issue?
