Win 10 forced update overnight disabled Brave; I reversed the W10 update. Then Firefox working well. “This site can’t be reached” and “no Internet”. DNS troubleshooting says “problem cannot be indentified”.
mail.yahoo.com’s DNS address could not be found. Diagnosing the problem.
DNS_PROBE_POSSIBLE
Reload does not help. I cleared Brave cache. No help. Closed and reopened Brave: no help. My ISP TWN tech support reports there is no problem on their end. Thanks for help.
