Is there anything you would like to know?
After signging to Teampel client, I can receive and send messages, but I can't download and upload files. What should I do?

1.On the Teampel server, in Windows Task Manager (Ctrl+Shift+Esc) > "Details", check if the Teampel FileServer (GaaihoFileSvr.exe) service is enabled

  • If it is enabled, please continue with the steps in 2;
  • If it is not enabled, please visit the directory: Teampel Server installation path/bin, double-click "GaaihoFileSvr.exe" or simply restart the entire Teampel Server.


2.On the Teampel Client machine, check if Port 35001 required by the Teampel Server GaaihoFileSvr.exe is communicating properly. If the Teampel Server IP address is, use the following command to check in Windows command line:

>Telnet 35001


When executing the Telnet command, if "Telnet is not recognized as an internal or external command" appears, please refer to the following instructions:

On Windows 7/Windows 8/Windows 10:

  1. Click "Start" > "Control Panel" > "Programs";
  2. In the left panel, click "Turn Windows features on or off" window;
  3. Click "Telnet Client":

  4. Click "OK" and wait a few minutes to complete the installation.


On Windows Server 2008 R2:

  1. Click "Start" > "Control Panel" > "Programs";
  2. In the left panel, click "Turn Windows features on or off" window to open "Server management interface";
  3. In the left panel, open "Feature", click "Add feature" to the right;
  4. In "Add feature wizard" window, click "Telnet Client", click "Next";
  5. Click "Install".
