If you are in Germany, Austria, Hungary, Italy etc. and the captcha takes ages to load, it's not just you. Telekom is having a dispute with CloudFlare over unpaid fees, and throttling their connection.

The captcha should get through eventually. Discord and similar services are going to suck for a bit, though. Mobile may or may not be affected, depending on the provider, and the right proxy/VPN connection can route past the bottleneck.

I'm also on a Telekom connection, and Hypnohub is borderline unusable without a VPN for me. I have measured the speed, and it's sometimes worse than dial-up. Discord is less bad, but especially gifs take ages to load on the bad days.
