Web Filtering Blocking All Connections

Hi. i have Installed my UTM 9 with bridge Mode. however when Web Filtering is ON, all the client cannot connect to Internet. then when it's disabled all the client can connect to Internet. I don't know what cause of this. can anyone help??

i do have tested with web tester policy, (ex access to manjaro.org) is successful, but when i try from my pc (IP Local) somehow failed. did i missing something??
