I've been using this generator for the past year, it does this but not super common. The last time it did this it was down for only a few days. just give it some time. come back in a day and test a response every few hours. I believe this happens when they are fixing stuff, messing with code, or probably fixing the website. but even if none of these are the case, I still like to think that it is. gives a happy positive while I wait for the bot to activate again. I'm just glad this doesn't happen everyday.
