I'm almost willing to bet it has to do with the VPN software you're using.  Make sure you set your DNS server to something like OpenDNS or googles free DNS service.

I am familiar with everything presented in this video, and my issue is that each of these commands and steps targets a completely different type of issue. The two netsh commands are frequently only required when a computer *should* be getting an IP address via DHCP (i.e. Local router and network are working and it's just the computer being dumb and nit accepting the IP offered). The flushdns command has no use right acter you turn on your computer, because the dns cache isn't retained when you turn off your computer (Caveat: If your computer is using Windows 10's Fast Boot, which is really more like Hibernation, then I don't know how it handles the DNS cache.)

 

Setting your IP address statically is a bad idea unless you know what you are doing and why. Setting your DNS servers to something more reliable like OpenDNS or Google DNS is a good idea.

I'm sorry? I haven't said anything that's really technical or advanced. You could read more about DHCP and DNS?

What VPN/proxy service are you using? And how are you connecting to it? Through your OS itself, or via a application (VPN's provided client or something like OpenVPN)? What kind of (brand/model) router are you using? You can go into your router and set the router's DNS servers to ones other than your ISP's. I prefer OpenDNS (208.67.222.222 and 208.67.220.220), Level 3 (209.244.0.3 and 209.244.0.4) and Comodo (8.26.56.26 and 8.20.247.20) DNS servers over Google's...because it's Google..

 

It sounds like your VPN client is reking your DNS settings. Sometimes you can do the 'diagnose problems' and Windows will fix itself. I had been using OpenVPN and a DNS leak script, but then I realized I can change the OpenVPN config files to prevent DNS leaks. With the script, if it didn't disconnect properly (or Private Internet Access's client's DNS leak protection) it would jack up the settings. Right click the network icon on your taskbar, click 'Open Network and Sharing Center,' click 'Change Adapter Settings' in the left bar thing (just under 'Control Panel Home'). Right click your network device (the actual device, not the TAP device) and select 'Properties.' Select the 'Internet Protocol 4 (IPv4)' setting (it should be checked by default, if not, that's a problem) and then click the 'Properties' button. Make sure the 'Obtain an IP address automatically' and 'Obtain DNS Server address automatically' options are selected. Most VPN clients will override these default settings to whatever it needs to connect to the VPN, if it doesn't disconnect correctly, they won't necessarily default back. That is also where you could manually specify your DNS server (put in the two IP addresses, or any combination of them that are listed above; the first one listed is the primary, the second is a backup for it) if you wanted to; but as I described, I would do it on your router rather than on your device.
