i try use proxy server with adguard. it seems to work fine except for websites that requires login and pass with http connection. it just can't login and give me some authentication message. Code: The following error was encountered while trying to retrieve the URL: http://forum.notebookreview.com/login.php? Cache Access Denied. Sorry, you are not currently allowed to request http://forum.notebookreview.com/login.php? from this cache until you have authenticated yourself. Please contact the cache administrator if you have difficulties authenticating yourself or change your default password. note : i provided adguard with my credential. adguard 5.5 could you fix this ?
