Windows 10: Ping OK but HTTP/HTTPS (mostly) failing

(Will mark as solved tomorrow if it has no further hiccups.)

 

Glad you got it sorted, Mark. I had to drop out yesterday to get some "real work" done. And thanks to Barman58, who definitely hit the correct nail square on the head. Best wishes for unimpeded Internet access going forward.

I've not used AVG for some years, after it started to mark some essential windows files as malware and either delete or quarantine them. They did fix the issue but I'd already moved to another solution.

I am not stating that AVG is a bad product, Indeed, I was one of the first people in the UK to use AVG Pro security, on the networks I was managing at that time, Back last century If I recall.

In those days AVG was a small East European start-up - A lot of Sysadmins did not trust a newcomer from that area, but I gave it a try and was very pleased with it for a number of years

 

Thanks all. Marking this one as solved now. Your help in nailing the issue is much appreciated!
