We use the Edge Client with client certificate authentication for our VPN users, since we have upgraded to APM Client version 7242 some of our users are getting an error message- "A certificate is required to complete client authentication".
The users have a certificate on their device and this has been working as expected up to this point.
Verify certificate installation: Ensure that the client certificates are properly installed on the users' devices. Double-check that the certificates are valid, not expired, and located in the appropriate certificate store.
Check certificate requirements: Review any changes or updates in the APM Client documentation or release notes for version 7242. There might be new requirements or configurations related to client certificates that need to be addressed.
Confirm certificate configuration: Verify that the certificate settings in the APM Client and the VPN server are configured correctly. Check the certificate selection method, certificate store locations, and any other relevant settings to ensure they align with your certificate deployment.
Remember to always follow best practices for troubleshooting and make sure to take appropriate precautions to protect the security and integrity of your VPN environment during the investigation process. If my suggestion work please accepet as solution.
