Content filtering question

[LakesideLion]

When I have a URL that's explicitly blocked, sometimes I get the Meraki message in the browser tab saying the network operator blocked it and sometimes I just get the browser message "this site can't be reached".   I haven't been able to figure out why the 2 different behaviors.  Can someone explain?

Hi @LakesideLion , is that behaviour seen using the same browser?

Hi ,

Why is the Meraki block page not displayed?

If the website you are trying to reach is using HTTPS/SSL (rather than HTTP), the browser will display an error page rather than the Meraki block page. Because HTTPS/SSL traffic is encrypted, the MX cannot decrypt and redirect HTTPS traffic to the block page. Instead, the request will simply time out (as seen in the image below).

That is probably the reason why.

Behaviour similar to what you’re seeing:
