Failed to Validate Client Certificate" Error with User ID Agent

[Jagdeep1]

Hi Community,

We’re encountering an issue with our Windows-based User ID Agent installed on the server. Specifically, we're receiving the error message: "Failed to validate client certificate: No connection found."

Here’s what we’ve tried so far to resolve the issue:

1. Verified Certificate Locations:

   • Checked Device > User Identification > Connection Security and confirmed there is no certificate present.

   • Verified that no certificate exists in the User ID Agent itself.

   • Reviewed the User-ID agent configuration file and found no certificates there.

2. Troubleshooting Steps Taken:

   • Attempted to upgrade the User ID Agent.

   • Reinstalled the User ID Agent.

Despite these efforts, the issue persists. We’re looking for any additional suggestions or insights from the community that might help us resolve this problem.

If anyone has encountered a similar issue or has ideas on what we might have missed, your advice would be greatly appreciated!

Thank you in advance for your help.

What certificate it might be referring to ? any ideas ?

Hello,

Same issue here, we had to add ans delete certificate for User-ID feature.

Then it reworks.
