   One of my computers is refusing to update, zypper says it cannot resolve   
   download.opensuse.org.  The problem was first seen around 14 hours ago   
   and an update had succeeded 48 hours before that.   
   It is the only system I have which uses Network Manager, it is also ipv4   
   only (hardware reasons) although in that respect it is not the only one.   
     Other xxx.opensuse.org sites *are* accessible to it.   
      
   I will have more time to attack this problem tomorrow, this query is   
   just on the off-chance that someone else has seen this.   
   My suspicion was name-resolution on the router - I set up DNS over TLS   
   (DoT) recently with the primary server being dns.quad9.net - but things   
   still worked for 48 hours after I made that change.   
      
   OpenSUSE 15.3 Leap, fully patched.
