Scenario: When accessing websites, I encnounter difficulties for connecting to websites, and it shows the certificate is untrusted.

Answer:

dnsft.cloud.zyxel.com is our blocked page for the DNS content filter, and the certificate is a content filter certificate that will replace the original cert when accessing a website in the content filter blocked category, resulting in the browser detecting the cert does not correspond to the correct cert, then you will see the message as this screenshot.
In conclusion, the website is blocked by DNS content filter, please check the content filter settings.
