OpenDNS not blocking sites - only one computer works

[smayer97]

Running OpenDNS updater on one mac with Snow Leopard 10.6.8. Sites block just fine.

IP address in OpenDNS Updater running on Snow Leopard mac matches dashboard.

BUT

Using macOS 10.14.4 Mojave on another Mac sites are NOT blocked!

2 other computer using Windows 10 and sites NOT blocked!

Checked Network settings DNS show 208.67.223.123 and 208.67.223.123

opening https://welcome.opendns.com/ gives Oops error message, OpenDNS "

You aren't using OpenDNS yet."

running command nslookup -type=txt debug.opendns.com. 192.168.0.1 gives

";; connection timed out; no servers could be reached"

Not sure what else to look for. Please help!

I wonder why they only post 2 of the 4 on their main page? Thanks for the info.

Because publishing 4 addresses would cause more concerns and questions, for example why there are 4 if one needs only two, and which ones would be the right ones if using less than 4.
