Smart Card driver does not work - electronic signature

Question

Hello everyone!
I connect via remote desktop to my server on which I have an accounting program installed (usb ports redirected). I have an electronic signature with which I want to sign documents, everything is fine until I choose a smart card. The signature certificate is visible, but no smart card driver works! I cannot sign documents that are important to me. Everything works on Windows 10. Unfortunately, the following message is displayed on windows server 2022:

Not only this driver does not work, but also the second omnikey. Are there any ways to do this? I have not had such problems with the remote desktop before.

Hi there,

This issue might occur if the smart card driver is corrupted or removed in the server.You need a driver for the smart card itself as well and the reader for it to work properly.

Also if you get this error with smart card authentication on your RDP session make sure:

-Smart card middleware is installed on both client and server.
-The same smart card reader drivers are installed on both client and server.
-The key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftCryptographyCalaisSmartCards contains your smart card and the key is not empty, containing an “Crypto Provider” REG_SZ filled with the CSP.
-Make sure the CSP mentioned above is defined under HKEY_LOCAL_MACHINESOFTWAREMicrosoftCryptographyDefaultsProvider and uses an existing DLL file.
-The above mentioned registry keys should be the same on client and server so a match can be made.
