Cat box is blocked by certain providers and carriers... that's your issue.
E.g. Verizon N.Am blocks cat box.
Catbox is currently blocked by some ISPs and filtered DNS servers. If you're a subscriber of British Telecom (BT), Vodafone, or some Australian/New Zealand ISPs, and are not using custom DNS servers, you will probably have issues. Additionally, Catbox has been blocked by Quad9 before. The question is, why are you still using ISP/filtered DNS servers? Consider using OpenDNS, Quad8 (Google DNS), or Level3.

Use a VPN or switch connections.
Same here, haven't been able to play any CatBox files for weeks, despite using a multi hop VPN.
