Certificate as Security Provider - Error message

Hello,

I'm currently evaluating RDM in our company. In my setup I chosen certificate as Security Provider. Therefore I created a self-signed certificate and installed it on my client for testing purposes. I didn't know what's the perfect place for the certificate so I chosen the trusted root certificates. Maybe there's the problem?

After a reboot of my client I often get the attached error message.

Only deleting and reimporting the certificate will help.

Any guesses?

Greetings

Daniel
