Network connectivity sketchy

[tucansam]

6.4.0, has been running great for a long time now.  

 

Very recent issue, within the last couple of days.  I installed a pi-hole, my two unraid servers still point to an outside DNS server, bypassing the pi-hole.  nslookup works from the command line.  Testing servers inside sab and sonar work using the associated "test server" buttons.  

 

However.... When I click on the Dockers tab, under the Version column, it shows a red triangle and "! not available."  And sab and sonarr haven't downloaded anything in days (the pi-hole was not installed back then).  

 

But under "Apps" I can search all the different unraid plugins and docker images etc.  So it seems like some network stuff is working, and some is not.

 

Very confused by this.

 

Any help appreciated, thanks.
