Hi megauwu,
I am Vijay, an Independent Advisor. I am here to work with you on this problem.
Try to change your DNS to either Google DNS or Open DNS and reboot your computer.
Windows Key+R > Type ncpa.cpl and Enter > Right click on your network > Properties > Select Internet Protocol Version 4 (TCP/IPv4) > Hit properties > Make sure below ones are checked
Google DNS
Select Use the following DNS Server Addresses > Preferred DNS Server - 8.8.8.8 > ALternate DNS Server - 8.8.4.4
OR
Open DNS
Select Use the following DNS Server Addresses > Preferred DNS server : 208.67.222.222 > Alternate DNS server : 208.67.220.220
Do let me know if you require any further help on this. Will be glad to help you.
