Possible errors in the use of the electronic certificate

Persistent 403 error due to antivirus blocking

If after performing all the checks related to the electronic certificate (expiration, installation, importing a copy, etc.), the error page 403 or similar continues to appear, in many cases it is the antivirus that is preventing the signature or causing the certificate selection window not to appear.

Below we show the most common antivirus check paths to review their configuration.

Kaspersky

Right-click the Kaspersky icon in the notification tray and select "Settings". If you open the Kaspersky panel, access the settings from the gear icon at the bottom left. Next, go to the "Advanced" (or "Additional") menu, "Network". Select the "Do not scan encrypted connections" option.

If you are installing on a Mac and the certificate selector does not appear, click the Kaspersky icon on the top bar and go to "Preferences". Next, within the "Connection" tab, in the "General" section, locate the box "Check secure connections ( HTTPS ) for Safe Money, Private Browsing and Parental Control".

Bitdefender Total Security

Go to "Protection", "Online Threat Prevention", "Settings" menu. Once inside the settings, locate the "Scan encrypted websites" box.

Avast

Open the antivirus and go to "Options" (gear icon located at the top right). Go to "Components" or "Active Protection" and locate the "Web Shield" option and click the "Customize" button. Locate the option "Enable scanning of HTTPS ".

On Mac, open the antivirus from the icon in the menu bar. Click on it and then click "Open". Go to "Preferences", "Shields", "Web Shield", "Options". Next, locate the "Scan private connections" and "Scan secure connections from browsers only" options. For some options you will be asked for the Mac user password.
