How to fix error error-connection-count-limit in Windows 11

Solution Steps

1. 1 First, try again later. The connection limit may be temporary if the server is busy.
2. 2 If you're connecting to a network share, close any unnecessary files or programs that might be holding connections. Use Task Manager (Ctrl+Shift+Esc) to see which processes are using network resources.
3. 3 If you're an administrator, you can increase the connection limit on the server. For Windows servers, this is done via the registry. Press Windows key + R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters. Look for a DWORD value named 'MaxMpxCt'. If it doesn't exist, create it. Set its value to a higher number (e.g., 50). Restart the server.
4. 4 On the client side, you can also increase the number of allowed connections by editing the registry. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management. Create a DWORD value named 'MaxUserPort' and set it to 65534. Also create 'TcpTimedWaitDelay' and set it to 30. This allows more connections and faster reuse of ports.
5. 5 After making registry changes, restart your computer. Then try the connection again.
