**Direct answer:** A CredSSP encryption oracle remediation error means your RDP client and the Windows cloud server have mismatched CredSSP security updates, so the connection is blocked to prevent credential exposure. The supported fix is to install Windows updates on both the local computer and the server, then reconnect with RDP. On a [Cloud Server](https://www.layerstack.com/en/vps) from LayerStack, use updated Windows Server images and keep both sides patched rather than permanently lowering the policy to Vulnerable.

## What is credssp encryption oracle remediation?

CredSSP encryption oracle remediation is the RDP connection block that occurs when the local computer and the Windows cloud server have mismatched CredSSP security updates. The connection is blocked to prevent credential exposure until both sides are updated and compatible again.

## What does "this could be due to credssp encryption oracle remediation" mean?

The message "this could be due to credssp encryption oracle remediation" means RDP stopped the connection because the client and server do not have matching CredSSP updates. Install Windows updates on both the local computer and the server, then reconnect with RDP.

## How do I fix a credssp error on a Windows cloud server?

To fix a credssp error, install Windows updates on both the local computer and the Windows cloud server, then reconnect. On a Cloud Server from LayerStack, use updated Windows Server images and keep both sides patched rather than permanently lowering the policy to Vulnerable.

## How do I fix an rdp credssp error?

To fix an rdp credssp error, update both the RDP client computer and the server, then try the RDP connection again. If the error continues after both sides are updated, check that both sides remain patched and reconnect, rather than leaving the policy set to Vulnerable.
