In this way, they can filter communication and cache data, as well as keep the IP address of the user secret from the contacted web server.
However, there are various scenarios in which a proxy server can cause problems like the ERR_CONNECTION_REFUSED error message. For example, the web server could block the proxy or its IP address and therefore reject the connection. Another possible source of errors is the caching function of the proxy servers – as soon as the cache contains obsolete data, connection errors cannot be excluded.
