Identifying proxy server problems

Sometimes Internet providers, who use proxy servers, can cause difficulties when connecting to particular sites. This generally occurs when the content that they store on the proxy server has expired or been overwritten with the wrong data. Secondly, if their proxy server does not support Secure Sockets Layer (SSL), this can cause difficulties. To resolve this problem you will need to contact your Internet service provider and ask them if they support SSL or are having any difficulties with their proxy server. In some cases they may need to refresh their content in order to display the page correctly.
