Skip information indexError 403. Internet Explorer and Windows with certificate
This is generally an identification error. It occurs when you try to access an option that requires an electronic certificate and the browser does not detect its installation or it is not selected properly.
These checks can be performed:
1. Restart the browser
To prevent the error from recurring due to being in the same session, it is recommended to completely exit the browser from "File", "Exit".
2. Check that the certificate is in the browser
- For software type certificates, go to "Tools", "Internet Options" of Internet Explorer. In the "Content" tab, press the "Certificates" button; If the certificate installation is correct, it should appear in the "Personal" tab. If it is not installed here, check if it is in another browser (for example, Mozilla Firefox) or if you have a valid copy of the certificate (with a .pfx or .p12 extension) to import it.
- If the electronic certificate is a cryptographic card (for example, DNIe ) close the browser, reconnect the reader and open the browser again to access the procedure.
If it is a DNIe and the browser still does not detect the certificate, follow the steps indicated in the help "Connection error with DNI in Windows".
For the rest of the electronic certificates such as cryptographic cards, it will be necessary to contact the issuing entity.
3. Check the validity date of the certificate
If the electronic certificate is not valid, it will be necessary to request a new one.
If there are expired certificates in the certificate store ("Tools", "Internet Options", "Content", "Certificates"), it is advisable to obtain backup copies of those that are current and subsequently delete the expired certificates.
4. Check if the electronic certificate is damaged
You must export the certificate to obtain a backup copy, checking the "Export private key" box.
The icon for a valid copy will be an open yellow envelope with a green certificate peeking out and a key, and with the extension .pfx or .p12.
- If you obtain a valid copy of the certificate, close all open Internet Explorer windows and then access the procedure that requires your electronic identification again.
- If the "Export private key" box is not active, check the note at the bottom of the window. If the message is " the private key is marked as non-exportable " close all open Internet Explorer windows and then access the procedure that requires your electronic identification again.
- If you cannot check the "Export private key" box and the note message is "associated private key not found" the certificate is corrupted. In this case, it is necessary to import a valid copy or request a new certificate.
5. Validate the electronic certificate
- If it is a software-type electronic certificate from the National Mint and Stamp Factory ( FNMT ) or an electronic DNI , it is advisable to install the " Configurator FNMT -RCM" available on the FNMT website, under "Obtain Software Certificate", "Pre-configuration". On the same FNMT website you can validate the certificate from the "Verify status" option.
- If it is an electronic certificate type cryptographic card, the validation is carried out from the REDSARA website.
If the certificate status is correct ("valid and not revoked", "valid certificate" or "the certificate is valid, including its revocation status"), access the Internet Explorer menu, "Tools", " Internet Options", "Advanced Options" and press the "Reset..." button.
6. Check your antivirus as it may be blocking the signature
If the problem persists after following these instructions, configure the antivirus so that it does not prevent identification with a certificate or temporarily deactivate it to carry out the electronic office procedure. Later activate it again.
