All of our proxies work only through binding to the IP address where your software is installed. Since the IP address of the proxy-checker is different from yours, the proxy data will be inaccessible for it. If you have specified login and password for access to your proxy, it is also impossible to check it with the help of proxy-checkers since most services do not have this function.
The easiest way to check them is to link the list to the IP address of the current device and check their work in any available browser. This is done for your security, so that this list is not used by someone else.
