So, recently, Chrome (on my Windows 10 laptop) began displaying the error "DNS server address could not be found" (DNS_PROBE_FINISHED_NXDOMAIN) for Facebook, Twitter, Instagram and YouTube.
All other sites work absolutely fine (at least the ones I use and can think of). Firefox and Internet Explorer both spit out errors, too, when trying to connect to these sites. All other computers in my home wireless network don't have this problem, and I don't think it has anything to do with my home network since connecting my laptop to a mobile hotspot still gives me the error when trying to visit the mentioned sites.
I tried clearing the hosts file, I tried flushdns, I tried disabling IPv6 – all to no avail. I ran a full security check on my PC with no results. This is frustrating, and I hope someone can help me!
Oh, by the way, I can still access the websites through the Tor Browser.

What happens when you try to access, say, FB by its IP address: 31.13.66.36?
I put that in my browser address bar and it loads the FB site but I can also load it from www.facebook.com. I'm wondering if you can load it with the IP but NOT the domain name. That would help rule in our out a DNS issue.
