As such, ngrok can no longer offer services to individuals based in those sanctioned countries. You can read more about these requirements on the United States Treasury website. ngrok also blocks agent connections from known TOR exit nodes and other anonymizing proxies, because using such services to hide your identity is against the ngrok Terms of Service.
