proxy authentication

[esicuwa]

I connect a proxy to create a link between accounts, but I still catch rate limits, etc.

 var config = SteamConfiguration.Create(b => b
     .WithHttpClientFactory((httpMessage) =>
     {
         var handler = new HttpClientHandler()
         {
             Proxy = new WebProxy($"http://127.0.0.1:{local_port_t}"),
             UseProxy = true,
             UseCookies = true,
             CookieContainer = new CookieContainer(),
             AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
         };

         return new HttpClient(handler)
         {
             Timeout = TimeSpan.FromSeconds(30)
         };
     })
     );

 SteamClient steamClient = new SteamClient(config);

and after that I already log in using a proxy, checked the IP and it matches the proxy, but I constantly catch rate limits and often letters do not arrive about authorization and binding

    CredentialsAuthSession authSession;

    authSession = await steamClient.Authentication.BeginAuthSessionViaCredentialsAsync(new AuthSessionDetails
    {
        Username = data_account.Login,
        Password = data_account.Password,
        IsPersistentSession = false,
        PlatformType = EAuthTokenPlatformType.k_EAuthTokenPlatformType_MobileApp,
        ClientOSType = EOSType.Android9,
        Authenticator = new UserEmailAuthenticator(mailCheckerMafile, data_account, Imap, local_port_t)
        
        

        //Authenticator = new UserConsoleAuthenticator()



    });
