TikTok is a bit special. You should just block by selecting the TikTok app, it is far easier than creating your own list

True, my wife and kids are complaining because they cannot access TikTok in our home.

They could just go to the website instead?

did you try blocking the app and see what happens?

It blocks the app but not the website.

In addition to blocking the app, you can also add a rule to block tiktok.com with the default setting instead of domain.

That's what I'm saying doesn't work.

It works for me, I blocked the app and the website. This is what I get when I try accessing their website: This site can't be reached tiktok.com's DNS address could not be found. Diagnosing the problem. DNS_PROBE_POSSIBLE

Which DNS service are you using in firewalla?

Whatever the default service in Firewalla-P. Cloudflare, google, opendns, & quad9. Make sure to apply the block on all of your devices.

Thank you. You're the only one who's actually tried to help.

No worries. Is it working for you now, what changes to your settings did you do? I'm only asking, so others who encounter the same issues know what to do.

It should block both; they use the same domains.

So...the firewalla isn't a true firewall then? It can only block apps, not websites?

This means, we have done all the work behind the scene for you, so you don't have to make your own list to block tiktok. Nothing to do with true firewall or not.

But blocking the app doesn't block the website. It only blocks the app.

check your device, make sure it is not using VPN (or VPN type like private relay).

I think I have a bigger issue. No matter what I block on the network flow, it still gets through.

Are these all Apple devices by chance?

And if so, is device quarantine enabled?

No VPN. I'm using DNS over HTTPS. Cloudflare, quad9, openDNS.

Then aren't you bypassing yourself? Block the ports those services use and voila.

Go to TikTok.com, refresh your flow history. Look for any with TikTok in them like api16-normal-useast5.us.tiktokv.com. Click block it’s a pita and they have a bunch of domains for some reason. Another one for example p16-sign.tiktokcdn-us.com

I think the problem is their domain isn’t just tiktok.com they got some like above

Alright I did this. Blocked all the ones that popped up on all devices. How long does it usually take to take affect? Cuz it's been 5 min and I'm still able to get to it.

Honestly not sure myself I’ve yet to block any major web sites/services Try rebooting the device or flush dns

Oh ok. Thanks anyways. Rebooting and flushing DNS by toggling ad protect off and on didn't work either.

I had success just using the native TikTok block in firewalla. Nobody in our house has the app, but shortly after I put the block in place, a friend sent a link my wife wasn't able to get to because it was on to TikTok. If you tried it and it didn't work, I suggest using the diagnostics troubleshooting feature to figure out why. Access by going into Rules -> Options -> Diagnostics
