GET root returned 503 Service Unavailable

Hello,

I'm getting this error on the log on the client side:

20140526 10314844 ERROR TSQLHttpClientWinHTTP(067C3460) POST root/ConfigcxGrids returned 503 Service Unavailable with message  Service Unavailable stack trace API 00678D5D 006B9B58 006BA020 006B5A13 006C60A8 00C81B24 01371419 013707DD 0062E164 01372FDB 01372A3D 014EDFC5 013D6D43 00556A5D 0055ABEE 00578B99 004D8B92 769986EF 76998876 769989B5

What does it mean this "503  Service Unavailable" error? how can I avoid it?

It means that the client did not succeed to connect to the server.

Re: GET root returned 503 Service Unavailable

When it happens, can I make the TSQLHttpClientWinHTTP try to connect again? How can I show a message to the user?

Re: GET root returned 503 Service Unavailable

See

    Client := TSQLHttpClient.Create(AnsiString(edtServerName.Text),'888',Model);
    if not Client.ServerTimeStampSynchronize then begin
      ShowMessage(UTF8ToString(Client.LastErrorMessage));
      FreeAndNil(Client);
      exit;
    end;

in sample "20 - DTO interface based service" and "14 - Interface based services" for instance.
