遇到错误407：代理服务器认证失败，如何解决？

Hey guys,
so i’m trying to access this site, but i keep getting 错误407: 代理服务器认证失败.
Anyone else run into this?

I’ve tried restarting my browser, clearing cache, and even resetting my proxy settings, but no luck.
Is there something obvious I’m missing?

Also, does this have to do with my network settings or the site itself?
Kinda frustrating cuz I need to get this done ASAP.

If anyone’s dealt with 错误407 before, pls share how u fixed it!
Thanks in advance, y’all 🙏
