Xfinity not allowing connection to any .mil site

Any site with a .mil address I get a This site can't be reached DNS_PROBE_FINISHED_NXDOMAIN message, has been happening for at least a month, it worked about 2 months ago. I have tried it on a MAC, Ipad, Android and windows 10 & 11 with multiple browsers, LAN or WiFi.  If I switch connection to my phones LTE data  it works and works if I use the phones data as a Hotspot for computers.  It does not show up in CyberSecure as a blocked page, and turning CyberSecure off has no effect also restarting the Gateway has no effect.  I have seen this reported here and on Redit, didn't see any resolutions I haven't tried.
