Security config and content filtering is not working. DNS resolver is. Did all the settings. Suggestions? Windows 10, TP-Link Router, Google Chrome, Comcast ISP.

Check if your IP address is registered at https://dashboard.opendns.com/settings/

Ensure that the Data Saver extension is disabled in Chrome. And flush your two local caches once: https://support.opendns.com/hc/en-us/articles/227988627
And ensure that you have configured IPv6 in case of IPv6 connectivity from the following list of DNS server addresses: ::ffff:d043:dedc ::ffff:d043:dcde ::ffff:d043:dede ::ffff:d043:dcdc

Still problems? I need more information. Copy & paste the complete plain text output of the following diagnostic commands to here:

nslookup -type=txt debug.opendns.com.
nslookup whoami.akamai.net.
netsh interface ipv4 show config
netsh interface ipv6 show dns

It looks like something (maybe your ISP, involving Leaseweb USA, Inc.) intercepts your DNS traffic and redirects it to somewhere else.

You may be able to circumvent this by using DNSCrypt (https://dnscrypt.info/). Or call your ISP to opt out from this DNS redirection.

Thanks, I tired this. I bypassed my TP-LINK AC1750 Router and went straight to my modem and it worked. Thoughts?

Not really thoughts. You configured OpenDNS on your computer:

 Statically Configured DNS Servers: 208.67.222.222
                                    208.67.220.220

This usually overrides DNS configuration on the router or modem. It may be that your TP-Link router did something with DNS traffic passing through, something like Comcast's Constant Guard or the Xfinity xFi app, both mentioned in the other thread I linked to. I do not have Comcast, Xfinity or any of the mentioned devices, so it's pretty hard to try it out and find it out here myself.
