Not able to log on with my iphone 6 plus (Read 32 times)

I recently tried to access myrunning  log remotely with my iphone 6 plus.  Noticed that I was logged out of my account.  When I enter my email address and password and hit enter, it keeps taking me back to the login screen again.  I've done it several times, making sure I'm carefully typing in the correct info.  It's odd, but I don't get an error message telling me that I entered my password incorrectly, it just goes back to the log in screen again.  I've tried changing my password and this hasn't helped, just keeps taking me back to the login screen.  Has always worked before with no issue.  I've noticed no problems on my desktop system.  Any advice on this issue would be appreciated.

Thanks,

Chris
