Open DNS Web Filtering stopped working after update to Mac OS Catalina
Hi
My issue is in the subject line. I've used Open DNS for years with scarcely a hitch, but when I updated to Catalina the other day it stopped filtering completely. I've removed my home network and re-added it, all the relevant buttons are checked, the IP address is correct, the DNS server addresses are present and correct in my Network settings. It all looks fine, but it's stopped filtering. Any ideas?
Many thanks
Glenn
PS: I also use the optional blocking software my ISP provides. I've been using it in conjunction with Open DNS for years and it's been fine. Nonetheless, Ive switched that on and off too while troubleshooting this problem but that made no difference either way.

The reason why your settings are not taking effect is that your IP address 88.144.104.134 is not registered at your dashboard at https://dashboard.opendns.com/settings/
