"Certificate file failed validation check" error message

Issue description

Starting at firmware level xx.222.031, a change was implemented for Common Criteria which requires the X509v3 constraint "CA:TRUE" field.

If a certificate does not have this constraint, then the error message “Certificate file failed validation check” appears when a user tries the user attempts to upload the certificate.


Contact your system administrator and request a reissued certificate from your certificate authority, signed with the "​​​​​​CA:TRUE​​​​" constraint. ​
