The last two days (Nov. 16 and 17, 2021). With my usual morning startup (same time as always).
VPN is on (I had to start it manually). (This also has been happening more often lately).
With VPN on, both browsers show the "Can't find the addresses". If I turn the VPN off, they work properly. Then , when I turn the VPN back on, it works properly.
Too many problems with Norton 360 over the last year (my first year using it). Just expressing my discontent.
Best Wishes.
