Since the Nintendo Switch has been out, the community is hard at work trying to find out ways to extend the possibilities of the device. The Switch’s browser is slightly hidden from the end users, but can be accessed with a few tricks and/or proxies. We’ve talked about DNSwitch already, although that technique did not seem to let people play Videos.
User driverdis at GBATemp has published a full tutorial on how to use a proxy on the Nintendo Switch, which will let you access youtube and play videos. He mentions that anything requiring to log in (including, but not limited to Youtube Red) will not work.
The tutorial covers two major proxy utilities: Fiddler and Charles Proxy. Feel free to use whichever one you want. In addition to using the proxy to redirect the console’s requests to youtube in order to access the site, it seems the trick is to have youtube believe the site is being accessed with an iPhone, I assume this is so that youtube sends the Videos in a format that is compatible with the Nintendo Switch (we’ve explained with DNSwitch how the Nintendo Switch seems to only support H264).
People have reported good success following driverdis’ technique.

People also report that Plex work fine with the Nintendo switch, with a similar Proxy setup. Again, this will only work for videos that are “local” from a share, not streamed (the Switch’s browser does not support streaming).
