Twitter ping inside proxy failed but when open from browser it open - proxy

Question

I have a problem: when I open twitter.com, it opens, but when use Tweetinvi it doesn’t work.
Therefore, I made this code:
var result = ping.Send("twitter.com");
if (result.Status != System.Net.NetworkInformation.IPStatus.Success)
{
insertlogwithFilename("test ping : 000X" );
}
I setup proxy configuration, but the ping does not work.
TweetinviConfig.CurrentThreadSettings.HttpRequestTimeout = 5000000;
TweetinviConfig.CurrentThreadSettings.UploadTimeout = 9000000;
if (noproxy == "0")
{
TweetinviConfig.CurrentThreadSettings.ProxyURL = "http://" + proxyIP + ":" + proxyPort;
}
try
{
Auth.SetUserCredentials(cuskey, secret, accesstoken, useraccessse);
}
catch (Exception exp)
{
insertlogwithFilename("error in authentication :" + exp.Message);
}
try
{
var authenticatedUser = User.GetAuthenticatedUser();
}
catch (Exception exp)
{
insertlogwithFilename("error in user authentication :" + exp.Message);
}
I test if connection to twitter is connected :
public static void testconn()
{
try
{
using (var client = new WebClient())
{
using (var stream = client.OpenRead("https://www.twitter.com"))
{
insertlogwithFilename("test stream : 8666");
}
}
}
catch
{
insertlogwithFilename("test stream : 8766");
}
}
this block of code return true
public static void testconnping()
{
var ping = new System.Net.NetworkInformation.Ping();
var result = ping.Send("twitter.com");
if (result.Status != System.Net.NetworkInformation.IPStatus.Success)
{
insertlogwithFilename("test ping : 8766" );
//return false;
}
else
{
insertlogwithFilename("test ping : 8666");
//return true;
}
}
this block return false

When you set up TweetinviConfig.CurrentThreadSettings.ProxyURL it does not mean that ping.Send will use this proxy. It means that Tweetinvi will use this proxy.
If you want to check if Tweetinvi is actually accessing the data, you will need to run the GetAuthenticatedUser method as explained in the documentation.
TweetinviConfig.CurrentThreadSettings.ProxyURL = "http://...";
ExceptionHandler.SwallowWebExceptions = false;
Auth.SetUserCredentials("CONSUMER_KEY", "CONSUMER_SECRET", "ACCESS_TOKEN", "ACCESS_TOKEN_SECRET");
var authenticatedUser = User.GetAuthenticatedUser();
