Help with logging in?

I’m trying to log in on the Pokègear to trade some pokes to evolve them, but when I try to log in with this username and password it doesn’t load. When I hit “C” to stop doing it, it says that “Username doesn’t exist”. And, well, it must exist cause I’m USING this account. Any help/suggestions?

Wait. I entered a different username of mine, and It worked? I guess I don’t need help anymore lol

What was the name that didn’t work? Quite a few inactive accounts were deleted sometime a year or so ago to improve database performance and clean up space.
