1. Trigger multiple operations on device.
   

2. The operation goes for approval.
   

3. Connect the Yubikey to the Operation signer laptop.
   

4. Approve single operation.
   

5. Verify operation is successful.
   

6. Unplug the Yubikey from laptop.
   

7. Connect the Yubikey again to the laptop.
   

8. Approve any operation.
   

9. Fortify prompt on approval page does not detect any certificate loaded on Yubikey.
   

Observations:

1. This issue is not seen with Fortify version 1.8.4

Thank you very much for the information provided. I have reviewed the logs provided and noted the following data:

I was surprised to see that the application uses libykcs11.dll from Program Files when connecting, but uses a library from System32 when disconnecting. This could be a problem with incorrect application behavior.

Also, I noticed that it would be beneficial to expand the logs and add information about provider identifiers, so we can monitor which provider was added or removed from the application.

I will try to reproduce the problem locally and will let you know when I have more information.

I have reproduced the problem locally. I am identifying the cause and making corrections.

I tried Fortify 2.0.2 test version provided by Ryan Hurst to verify the issue fix. [Test version Fortify app: https://drive.google.com/file/d/1IjTllOs769yhqcrxSS_RUCfM8iSgLRhE/view?usp=sharing]

I observed that Fortify Client is not detected while approving the operation.

Thank you for testing the update and providing the report. I have tried installing the version provided via the link and replicated the Yubico token connection. It worked without any issues on my end. However, there are a few things in the logs you've provided that caught my attention:

1. No Record of the Site Connecting to the Fortify Server
   There should be log entries indicating the connection between the site and the Fortify server. If you search for the word "origin," you should see entries like:

   {"message":"Create a new connection","source":"server","origin":"https://tools.fortifyapp.com"}
   {"message":"Push session to stack","source":"server","origin":"https://tools.fortifyapp.com"}
   

   This might indicate an issue with the server not starting correctly or a problem with the SSL certificate installation.

   To manually verify that the server is running and the certificate is installed correctly, you can visit the local link:
   https://127.0.0.1:31337/.well-known/webcrypto-socket

2. Fortify Application Detects Yubico Token Connection and Disconnection
   According to the logs, the Fortify application is detecting the connection and disconnection of the Yubico token. The logs contain entries like:

   {"message":"PKCS#11 library information","source":"provider","library":"C:\\Program Files\\Yubico\\Yubico PIV Tool\\bin\\libykcs11.dll","manufacturerId":"Yubico (www.yubico.com)","cryptokiVersion":{"major":2,"minor":40},"libraryVersion":{"major":2,"minor":52},"firmwareVersion":{"major":1,"minor":0}}
   {"message":"Crypto provider was added to the list","source":"provider","library":"C:\\Program Files\\Yubico\\Yubico PIV Tool\\bin\\libykcs11.dll","name":"Yubico Yubikey 4 OTP+U2F+CCID","reader":"Yubico YubiKey OTP+FIDO+CCID 0"}
   {"message":"Amount of tokens was changed","source":"provider-service","added":1,"removed":0}
   
   {"message":"Token was removed from the reader","source":"pcsc","reader":"Yubico YubiKey OTP+FIDO+CCID 0","atr":"3bfd1300008131fe158073c021c057597562694b657940"}
   {"message":"Token was removed from the reader","source":"provider","reader":"Yubico Yubikey 4 OTP+U2F+CCID 0","name":"Yubico Yubikey 4 OTP+U2F+CCID","atr":"3bfd1300008131fe158073c021c057597562694b657940"}
   {"message":"Crypto provider was removed from the list","source":"provider"}
   {"message":"Finalize crypto provider","source":"provider"}
   {"message":"Amount of tokens was changed","source":"provider-service","added":0,"removed":1}
   

Please check that the Fortify application is running properly and that the Fortify server is operational. I verified the connection/disconnection through https://tools.fortifyapp.com/. This site dynamically displays the list of connected devices.

Hi,

Thank you for providing the insights.
I checked on link https://127.0.0.1:31337/.well-known/webcrypto-socket, that the server is running fine.
I am able to approve the operations after unplugging and plugging the Yubikey to the host laptop.

Issue is not seen with Fortify test version 2.0.2 (https://drive.google.com/file/d/1IjTllOs769yhqcrxSS_RUCfM8iSgLRhE/view?usp=sharing)

Please merge these changes into official Fortify release so that we can test with official Fortify release.
