This is generally an identification error. It occurs when you try to access a telematic procedure that requires an electronic certificate and the browser does not detect its installation or it has not been selected properly.
Verify certificate installation
For software-type electronic certificates, go to "Edit", "Preferences", "Privacy and security", "Security", "Certificates", "View certificates", "Your certificates" and check that the certificate is correctly installed. If it is not installed here and you have a valid copy of the certificate (with a .pfx or .p12 extension), you can import it.
Check certificate validity date
Check the validity date of the certificate. If it is not valid, it will be necessary to request a new one.
If there are expired certificates in the certificate store, it is advisable to obtain backup copies of those that are current and later delete the expired certificates.
Check certificate status
If the electronic certificate is a cryptographic card (for example, DNI electronic) close the browser, reconnect the reader and open the browser again to access the procedure. If it is an electronic DNI and the browser still does not detect the certificate, you must follow the instructions in the help "Connection error with DNI electronic on Linux".
For software type certificates of the FNMT and electronic DNI , the "Verify status" option is available on the FNMT page .
If the result of the verifications is a valid certificate, clear the browser's recent history from the top bar "History", "Clear recent history" and check at least the "Cache" and "Active sessions" options.
If it is not possible to validate the certificate (message "Cannot display page" or similar) clear the recent browser history by checking all options except "Browsing and download history" and "Forms and search history" and "Cookies ".
If the certificate belongs to an entity other than FNMT the verification is carried out from the REDSARA website. If the result is not valid, it will be necessary to contact the issuing entity.
