We recommend using SOCKS5 proxies for uTorrent. When using HTTP, HTTPS, and SOCKS4 protocols, users often encounter technical problems when downloading files. They may simply not be loaded on the device. It is also worth noting that SOCKS5 is the best anonymizer, which hides all the data of the computer.
Before choosing a proxy server provider, it is recommended to pay attention to the parameter "traffic limit". If there is one, money will be deducted from your account. To avoid loss of money, it is better to choose a vendor who has to pay not for traffic, but for the number of addresses.
In the browser menu (top right corner), find "Settings", and then, under "Network settings", go to "Settings" to select "Manual network configuration". Enter, depending on your network protocol, the IP address, the port and click on "OK". Open any website and in the window that appears, enter the proxy password and login, then click "Ok" again. A successful connection to the site means that the setup is successfully completed.
In e-mail, proxy servers are used for secure data exchange as well as for collecting e-mails from several e-mail addresses at once. For example, this is how Gmail works, which also allows you to receive e-mails from mail.ru and other e-mail services.
In data centers, proxies are used to provide IP to virtual servers. After all, one server there can be used by a dozen users at the same time. And each needs to be allocated its own IP and port. All this is done through proxies.
If your proxy gives you a 504 error, it means the server failed to complete the request within the time period you specified. Refreshing the page may help. Another option is to switch to another browser. You can also use the incognito mode, pre-clearing the browser cache. Pay attention to plug-ins that can also cause this error.
