When connected to the Guest SSID, a certificate error page is displayed on your screen.

When connected to the Guest SSID, you may encounter a certificate error page, which could be caused by several issues that affect your network's security and authentication.

Before starting, why should you use a certificate?

TLS/SSL certificates secure internet connections by encrypting your data. They ensure data is transmitted privately, without modification, loss, or theft. Adding a certificate to your network environment will ensure a safer internet experience for your users.

Possible causes of the certificate error page include:

• Some browsers might block authentication on HTTP pages. 
• SSL Certificate is invalid or expired on your network equipment

• SSL Inspection is enabled, leading to a man-in-the-middle attack by the browser.

To address this issue, you can take several actions, including:

• Adding a valid certificate from a public certificate authority to your wireless controller or access point will permit access to HTTPS pages and enable your users to authenticate securely.
• Checking the validity and chain of your SSL certificate.

• Disabling SSL Inspection for testing purposes.

Following these actions, you can troubleshoot the issue causing the unexpected error page and give your network users a seamless and hassle-free experience when connecting to the SSID.

If you still have the error page issue after following these recommended actions, please don't hesitate to contact our team (How to contact your support? ) to make the necessary changes to your captive portal.
