Why am I getting the Remoteapp disconnected security package error?

There are multiple reasons for this error, and the most common are your registry values. If the app isn’t properly configured in registry, you may encounter this issue. It’s also possible that there’s an issue with your credentials, so removing them and adding them again can help with this problem.

How can I fix the security package error on Windows 11?

1. Delete the RDP connection cache in your registry

Each user’s registry stores information for every RDP connection. Using built-in Windows tools, removing a computer or computers from the list of RDP connection history is impossible. The above steps are taken to get rid of the registry keys manually. Once the steps are completed, the security package error message may be resolved.

2. Clear the saved RDP credentials

Note that if you select the option to Remember me before you enter your password for a new remote RDP connection, your credentials (username and password) will be remembered in the Windows Credential Manager. The RDP client utilizes the previously remembered credentials for authentication on the remote host for subsequent connections. Clearing these credentials may resolve the security package error. 

3. Disable Remote Desktop bitmap caching

Note that image persistent bitmap caching is included in the RDC (Remote Desktop Connection) client. As a raster image cache, the RDP client caches rarely changing parts of the remote screen. The mstsc.exe client uses this to load elements of the screen from the local drive cache that haven’t changed since the last rendering. The RDP caching feature reduces the quantity of data sent across the network. When using the RDP cache, it may be damaged. Disabling persistent bitmap caching may also be beneficial. SPONSORED
