yeah it happens with all of the names i've tried before. I tried using "rem" a few times as a sort of test name while trying to find what was wrong myself. Sadly i'm no good at programming yet. Hope this helps :)
I looked into it and it seems like you were failing to connect to the User-Agent string website. It might have been a problem on their end (I can ping it but I can't get to it in a browser so who knows what they're doing), but it might have been your own internet. I don't know what to say beyond that. If you're willing to try again, I'll be uploading a new version in a few days that might work better for you. Sorry for the inconvenience.
