Electronic certificates on iOS mobiles
Skip information indexiOS Error 403
The 403 error on devices with IOS system can be due to 3 main causes:
-
There are no valid certificates on the device. The certificate may be expired, revoked, corrupted, or an invalid copy (.cer) is provided. It is also possible that you do not have any certificates installed in the IOS certificate store ("Settings", "General", "Profiles"). If the "Profiles" option does not appear, there are no certificates installed.
Both downloaded root certificates and personal certificates are displayed in "Profiles". Select a certificate and press "More details" to check the validity date.
Verify the correct functioning of the certificate on the issuing entity's website. If you are from FNMT access with Safari to: https://www.sede.fnmt.gob.es/certificados/persona-fisica/verificador-estado and check the information related to the certificate. If the certificate is correct the message will be "Your certificate has just been verified. You are in possession of a digital certificate FNMT Valid and not revoked . Your certificate is working correctly."
-
You are using a non-recommended browser .
The supported browser is "Safari" since "Google Chrome" and "Mozilla Firefox" do not manage certificates on IOS systems.
-
The certificate was not correctly selected in the signing process.
Restart the browser and select the appropriate certificate at the time of signing. When you exit an application, for example the browser, it may not be closing completely. Normally the process remains active. To close the browser use the task manager. To open the task manager, quickly press twice on the start button that is located by default (depending on the version) at the bottom. Drag the app out of that list and it will be completely closed.
We recommend deleting temporary files and cache from the browser so that the error is not repeated because it is stored in memory. In Safari, go to the system's "Settings" menu and select "Safari." Then click on "Clear history and website data" and press "Clear history and data".
After correctly restarting the browser, if the 403 error occurs again after the previous checks, go back to the previous window using the arrow and access the same procedure window again. In this way, it is now possible to choose the correct certificate.
