OK guys
Try this, it worked for me when all the other fixes failed.
First, for my network adapter in IPv4 properties I changed my DNS from my ISP router, Automatic DHCP will assign this normally same as you default gateway.
- The change I made was to manually set the DNS to 1.1.1.1 as primary and 8.8.8.8 as secondary
The other change I made was to disable IPv6
Control Panel > Network and Internet > Network Connections right click on your Ethernet adapter > Properties and scroll through the list and uncheck Internet Protocol Version 6 (TCP /IPv6)
- If you used IPv6 only then don't do this obviously
Make sure to open your CMD in admin and ipconfig /flushdns
It's been working for me since.
Let me know if this worked for you guys 🙂
