Captive Portal Blocking Traffic

[wrlangston]

I set up a fairly simple guest network with one FG80F and two FAPs. Per company standards, I have to implement a Captive Portal. When I initially configured the SSID, it was "open" security mode with a "Disclaimer Only" CP, and it would redirect to the facilities website when you accepted the terms and conditions. I tested it myself when I was on site and it worked perfectly. 

A week goes by and the site rep contacts me explaining that users can't connect to the internet. They get the splash page, click accept, and then nothing. He tested it himself and sent a pic of the result (see attached). I found that disabling the CP lets users connect just fine, which leads me to believe there's some issue with the redirect. I don't know why it would be working one day and stop the next.

I've gone over my configs several times and nothing jumps out at me as a possible cause, but I'm still fairly new to Fortinet, so I must be missing something. Thoughts?

Which FortiOS version?

Once you click Accept and get the error page, did you try access any site on internet? Does it work?

FortiOS is 7.6.4 and as far as I'm aware, no one can access anything following the error page.

I figured it out. I forgot that I tried to implement a different splash page than the default disclaimer, and the HTML was wrong.
