Proxy servers may not work if the binding to the IP-address is set incorrectly in the personal cabinet and the connection port was not correctly specified when setting up the proxy.
To update IP binding, go to your tariff page and set IP binding (specify the IP address from which you will work with the proxy, you can find out through whoer.net) and click on the «Set» button.
To run a proxy with passwordless access, you must use port 8085 or 1085. To run a proxy with login authorization with password you must use port 8080 or 1080.
If after purchase your proxies worked, but after some time they stopped working, you need to go to the client panel and on the page of your tariff update IP binding. This problem can occur if the IP address from which you used the proxy has been updated.
