Yes!, I picked a random france number from quackr but the message is never received. Futher debugging I realize that the request that sends the message returns a 521 status code.

Try different France number then. Someone might have been using the same phone number or likely it has been blocked by CSDN itself.

The VPN you use, is using China?. Its a guess that the location might be the problem, or maybe the website is trully down 😅 @kiraio-moe

I can't truly remember what server I use when I signed up at that time. I used USA, Singapore, France, UK.
