Method 1. Update the TLS Cipher Suite

Even after upgrading to TLS 1.2, you have to make sure that the cipher suite settings match Azure Front Door requirements because Microsoft 365 and Azure Front Door provide slightly different support for cipher suites. To fix Error Code 0x8004de40, use the Enable-TlsCipherSuite cmdlet to enable the TLS cipher suites.

1. Hold down Windows+R keys to open Run.

Type PowerShell and hold down Ctrl+Shift+Enter keys to open PowerShell as an administrator

2. Type PowerShell in Run and hold down Ctrl+Shift+Enter keys to open PowerShell as an administrator.

3. In the PowerShell window, type in:

Run the Enable-TlsCipherSuite -Name “TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384” -Position 0 command

Enable-TlsCipherSuite -Name “TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384” -Position 0

4. Press Enter. Running this command will add the TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 cipher suite to the TLS cipher suite list at the highest priority.

5. Then type in:

Get-TlsCipherSuite

6. Press Enter. This command will verify the order of the cipher suites.

Method 2. Enable TLS 1.0, TLS 1.1, and TLS 1.2 Protocols

TLS is a security protocol that facilitates the establishment of encryption channels over the network. Hence, the TLS protocols help your OneDrive client and its servers communicate securely across a network. If either TLS 1.0, TLS 1.1, or TLS 1.2 is disabled, you may get the error code 0x8004de40.

2. Type inetcpl.cpl in Run and click OK.

Select Connections and click LAN settings

3. In Internet Properties, select the Connections tab.

4. Click LAN settings.
