So, since yesterday my youtube app decided that it never loads videos anymore, just endlessly trying to buffer them and then "connection to server lost".

What I did to fix this:

• factory reset
• reinstalled app
• deleted cache in app\youtube + app\google play service while it was disconnected from the internet
• modified my wifi connection so it runs from 8.8.8.8 DNS
• tried cable connection, same problem
• other applications work perfectly (netflix, twitch)
• youtube works from the builtin browser in the TV
• youtube works on everything else (two pc, three mobile phones all android)
• force stopped app and cleared cache everywhere else too
• there are no updates nor anything happened to the TV
• it's always "Connection to server lost"

My internet connection works perfectly, same to my router. Only the god damn youtubeapp on my tv is what doing this and I have no idea why. I got no adblock installed or anything like that.

Odd thing: It can't load new videos, but sometimes can load old (like 5th months) videos. Rarely loads new videos (2017 jan\feb) and plays them. Or just loads a tiny bit then goes "connection lost to server".

I live in germany, Kabel Deutchland internet, tv is a Sony KDL-50W755C. Latest firmware and everything. Anyone knows what is the problem or how can I fix this? Thanks in advance!
