Duckduckgo not resolving with Safe Search enabled

Hi,

I'm a new owner of a FWG.  I would like to enable the Safe Search feature for all of my devices.  The issue that I'm running into is that my FWG is not resolving duckduckgo.com when Safe Search is on.  I only get:

This site can’t be reached

duckduckgo.com’s DNS address could not be found. Diagnosing the problem.

DNS_PROBE_POSSIBLE

All of my searches turned up in FW help turned up nothing.  Everything says Safe Search for DDG should behave properly.

Thanks

  Did you search for "duckduckgo.com" or you type https://duckduckgo.com? try the later one and see.  Safesearch will only block search ..

  I'm entering the URL, and it doesn't work.  The embedded search in my Brave browser also won't work if I have DDG selected as my default engine.

  I manually typed in safe.duckduckgo.com - that worked.  Then I tried https://duckduckgo.com again, and it appears to work.  Maybe the safe DNS wasn't registered previously and going directly there helped?  I don't know.  It's working for now, so we'll see.

  Thanks

  OK - that "fix" is not reliable.  Right now I have a tab with safe.duckduckgo.com open and working, but duckduckgo.com is not resolving.

  What exactly does FWG do when Safe Search is enabled?  How does it redirect?

  More data...

  With Safe Search OFF I can ping duckduckgo.com and get a reply from 52.149.246.39.  I can also ping safe.duckduckgo.com and get a reply from 52.149.247.1.

  Once I enable Safe Search and ping duckduckgo.com - initially I see "Ping request could not find duckduckgo.com."  That is persistent until I follow this next step.

  If I ping safe.duckduckgo.com, I get reply back from 52.149.247.1.

  Then if I go back and ping duckduckgo.com again, I get replies back from 52.149.247.1 (the safe server).

  All of that makes sense except for the ping to duckduckgo.com initially not finding the host when Safe Search is enabled.

  Are you using Windows? Firewalla will return CNAME safe.duckduckgo.com to the DNS query for duckduckgo.com when SafeSearch is enabled. There is an issue that Windows won't continue to send DNS query for safe.duckduckgo.com.

  Yes, I'm using Windows.  Are you saying there is no way to fix this?

  Is this true for only DDG, or will this be the behavior of all the platforms for the Safe Search feature?

  Only Duckduckgo will encounter this issue.
