Windows 10: Can't connect to twitch.tv

I haven't come across any other website I am unable to connect to other than twitch.tv. I can connect on another computer in the house and also on my phone which is using the wireless router while I am using a wired connection to the same router. I've tried a quite a lot already like flush dns, editing the hosts file, reseting modem and router, updating ethernet drivers, disabling virus protection, disabling firewalls and trying 3 different browsers. I am at a loss and can't figure it out. When I attempt to reach twitch.tv I receive on chrome:

This site can’t be reached

Twitch took too long to respond.
ERR_CONNECTION_TIMED_OUT

:)

 

Sound not working Properly

Some things/websites work fine and the sound is perfectly normal. But using other things such as Twitch.tv or the League of Legends launcher, the sound has distortion over it. I even opened Twitch.tv on Firefox rather than chrome and it works fine on there.
I've tried everything I can think of, checking/reinstalling the drivers, checking if it was the browsers fault, checking updates on windows and other programs etc. Nothing seems to work. This seems to have started to occur after I installed an update for windows
the day before.

 

problems while playing videos on windows 10

I have noticed this problem occurs on my 2013 Sony Vaio Pro 13" only when the power is connected. Sites like Twitch.tv are fine, but Steam streaming and Youtube all suffer this problem when plugged in.

Edit: I have found youtube videos work in Firefox when plugged in, whereas in Chrome they do not.

 

I'm having the same problem but with different sites. mlahandbook.org and wpac.epls.org/polaris and it happens in every browser.
