I hope someone can help.
We have set up application control and web control to block tik tok on 30E ( 6.2.10 firmware).
After setup all looked ok ( around half a year ago) . Now it is not working properly. When you try to access tik tok from Imac safari , it blocks it , but on the phone and ipad App and safari open tik tok.
We made sure that 4G is off on devices and only WiFi is on.
Now have tested problem in my office ( thou here we have Fortigate 40F, 7.0.5 firmware) , but if all is set up earlier, there is no problem. But if you turn off the application control and turn it on if you have safari on ( even without tik tok on) tik tok works . Even thou application control logs show tik tok was blocked. . Same problem with application. Similar issue is with coming off the 4G and getting only to wifi , if you had app on it keeps working.
Tried to block IP’s but tik tok uses local ranges , and if you block most popular IP’s it uses , it switches to different ones.
I tried DNS filtering but that did not work at all.
Any suggestions would be appreciated.
