In the EDR Console > Admin Settings > Server Certificates > Add Certificate, an error occurs "Duplicate certificate is not allowed"
EDR Server: 7.x
The private key and public certificate files that have been uploaded to the EDR Console already.
Regenerate new private and public key pairs, then add the new files to the EDR Console.
To check certificate files use:
openssl x509 -noout -text -in <certificate filename already loaded>
openssl x509 -noout -text -in <certificate filename attempting to load>
New certificate file pairs (key, crt) being loaded must be different from the certificates that already exist in EDR.
