RDP connection error (Encryption error)

5 solutions to fix “Because of an error in data encryption” RDP

To tackle the "Because of an error in data encryption" RDP predicament, consider these five pragmatic approaches:

Solution 1. Configure the NIC properties on the remote side

Windows includes a feature known as Large Send Offload (LSO), designed to enhance network performance. Although well-intentioned, this feature inadvertently contributes to the issue of excessive network bandwidth consumption by background applications, ultimately causing a decline in Internet speed. To rectify this, you can take the following steps to disable LSO:

Step 1. Hold down the Windows logo key and press R. In the "Run" dialog, type "devmgmt.msc" and hit Enter.

Step 2. Locate and double-click on "Network adapters," then select your specific network adapter.

Step 3. Access the "Advanced" tab, proceed to click on "Large Send Offload V2 (IPv4)," and adjust the value to "Disabled."

Solution 2. Delete the Registry certificate keys

If the RDP “Because of an error in data encryption” issue persists, delve into regedit.exe on the target server and delete the Registry certificate keys.

Step 1. Open the Registry Editor by typing "regedit" into the Run box and pressing Enter.

Step 2. Go to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > TermService > Parameters.

Step 3. After exporting for safety, proceed to delete the certificate keys.

Step 4. A restart may unveil the resolution.

Solution 3. Reset Network settings

Resetting network settings can often work wonders. Execute the following commands via CMD.

Step 1. Run Command Prompt as an administrator.

Step 2. Perform the subsequent commands individually:

• ipconfig /flushdns
• netsh int reset all
• netsh int ip reset
• netsh winsock reset

Solution 4. Turn off UDP on Client

Enable the option "Turn off UDP on Client" could potentially iron out the connectivity issue.

Step 1. Type “gpedit.msc” into the Run box and press Enter to open Local Group Policy Editor.

Step 2. Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client > Turn off UDP on Client.

Step 3. Double click Turn off UDP on Client, and choose Enabled.
