I have Ubuntu and archlinux running on different boxes. Along with and Android phone. which i can't open Facebook or Youtube in the browsers (Firefox, Chrome). Error message: Server not found.
I can browse all other website I could try. https and http.
One of the boxes dual boots Windows 10. On that installation I was able to access both normally. Other computers in the house using the same router and Internet connection which has Windows and OS X are able to browse both websites normal.
I have changed my DNS settings to GoogleDNS and OpenDNS which in both cases didn't solve the problem. I have tried the drop the MTU values and it did work. I have restarted the router multiple times and it didn't work.
I can ping facebook.com and youtube.com and the packets are normal. I have managed to open m.facebook.com and it works normal but not m.youtube.com
this is a $dig www.facebook.com
