You are not stripping spaces at the end of login names in your app (sorry to ping you here but saw your reply and it reminded me to ask)
I couldn't get logged in to connect, or liftoff, then noticed I had a space (From selecting the suggestion on my phone). Didn't catch it until just now trying to login to liftoff. I've seen a couple complaints about getting logged into these apps. Wonder if I'm not alone with the extra space.
