Web challenges, instance not loading.

Hello friends,

Web challenges worked for me one week ago.
But it stopped working a few days ago.

I tried launch from different cities ( I`m traveling )

From different PC (Mac OS, Windows 10 and Linux on VMware ) doesn’t work, but web-challenges works for my friends

Docker works with Hotspot Shield (VPN), but why? If it worked for me before.

Error ( main system ): This site can’t be reached
docker.hackthebox.eu took too long to respond.

Error ( Kali Linux on VMware ): This connection has time out

Please, help me

Sorry for my English.
