Ok, what I think you’re seeing is something we’ve heard about from other European Glitch users - some European ISPs are blocking access to glitch.me domains. We’ve mostly seen this from Vodafone IT, but have also heard from some other folks from other ISPs. Unable to access *.glitch.me websites is a topic that discusses it and solutions that others have come up with - unfortunately we at Glitch can’t do much to help with this, but perhaps if enough customers complain to their ISPs someone will take notice.
Sorry for the bother!
