Firefox can’t find the server at www.reddit.com.
Check the address for typing errors such as ww.example.com instead of www.example.com
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

Edit: Almost forgot, this seems to have started after I tried installing PlayOnLinux the other day. I uninstalled it but the problems persist.

Any thoughts?

Не надо. Это неумные люди, не способные разобраться в проблеме, советуют.

Попробуйте отключить IPv6.
И не забывайте указывать, ГДЕ вы эту ошибку встречаете.

P.S.
Если не поможет отключение IPv6 – звоните провайдеру и насилуйте ему мозг. Скорее всего, их DNS сбоит.

What is DNS_PROBE_FINISHED_XDOMAIN Error?

DNS helps direct the incoming traffic by connecting the domain names with the web servers. This domain name gets converted into the IP address to be understood by the computer. This error commonly occurs when there is a mistake within the configuration or any issue with the DNS. The actual problem occurs when you provide the URL, and the DNS will not be able to search the server with an appropriate IP address regarding that server. Whenever the DNS fails to explore, it results in an error called DNS_PROBE_FINISHED_NXDOMAIN, where NXDOMAIN represents the non-existent domain. 

There is nothing to worry about as it is easy to fix, and the solution comes in many ways suitable to you. Well, different browsers serve you with different ways of solving the problem. This error name is mostly for Google chrome, but that does not mean this error does not occur on other browsers.

I am using Ubuntu 14.04 64 bit with a wired connection. For the last 7 days, I have been unable to open Github. It instead has an error.

Is there anything wrong with my connection / hardware / network / browser settings or in website itself?

Chrome gives This webpage is not available with below details

The server at github.com can’t be found, because the DNS lookup
failed. DNS is the network service that translates a website’s name to
its Internet address. This error is most often caused by having no
connection to the Internet or a misconfigured network. It can also be
caused by an unresponsive DNS server or a firewall preventing Chromium
from accessing the network. Error code: DNS_PROBE_FINISHED_NXDOMAIN

Firefox gives Server not found

P.S. no firewall software installed on my system.

I had the same problem on a different platform. I was using windows 8.1 when I suddenly could not access github anymore, this error came right after creating a site on github pages.

I solved this by flushing my dns cache.

Type this in the command promt:

ipconfig /flushdns

On ubuntu just: right click on your connection on panel (top right on unity by default) and click configure network connections. Then right click on your wifi -> click edit -> go to IPv4 (you may need to extend the window to see it), and in “Other DNS servers” type: 8.8.8.8,9.9.8.8 and click OK.my settings on my Kubuntu (KDE instead of Unity)
