Digital certificate: common mistakes and how to prevent them

08 Feb 2026

The certificate must be installed together with its private key, and it is advisable to keep a protected copy. Many failures occur when importing an incomplete file or using a browser other than the one that contains the certificate.

Before renewing, formatting, or changing equipment, verify that you can export it correctly. If an error already appears, we check the certificate store and the configuration without sharing your keys.
