Cannot Access Web Config

If you cannot access Web Config on your product, try these solutions:
• Make sure your product is turned on and connected to your network using the correct IP address.
Verify the connection using your product control panel.
• Make sure your browser supports the Encryption Strength for SSL/TLS. If you selected High as the
Encryption Strength setting in Web Config, your browser must support AES (256-bit) or 3DES (168-
bit) encryption. Check your browser's encryption support or select a different Encryption Strength
option.
• Check to see if your CA-signed Certificate is expired. If there is a problem with the expiration date of
the certificate, "The certificate has expired" is displayed when connecting to Web Config with SSL/TLS
communication (https). If the message appears before its expiration date, make sure that the
scanner's date is configured correctly.
• If the common name of the certificate and the scanner do not match, the message "The name of the
security certificate does not match" is displayed when accessing Web Config using SSL/TLS
communication (https). For Self-signed Certificate, update the certificate. For CA-signed Certificate,
take the certificate again for the scanner.
• If you are using a proxy server with your product, configure the browser's proxy settings as follows:
• Windows 11: Click
proxy server to On.
• Windows 10: Click
proxy server to On. Select Don't use proxy server for local (Intranet) addresses.
