I have couple of wifi connections out of which one works fine whereas the other one only works for some of the websites and services like google.com & skype. Browsing rest of many websites usually gives me that error:
DNS_PROBE_FINISHED_BAD_CONFIG
I rarely get following errors as well:
DNS_PROBE_FINISHED_NO_INTERNET
DNS_PROBE_FINISHED_NXDOMAIN
Another very strange thing that I experienced is that repeatedly refreshing a page often opens it whereas it doesn't apply at every web page.
I found many solutions as an outcome of long searches at Google & Stack Overflow but none of these worked. This is not a browser particular issue as getting the same issue on all the browsers I've (i.e. Chrome, Mozilla & IE). I'm getting the same issue at my official machine with Ubuntu OS & personal machine with Win10 OS. Meanwhile I've no problem with web surfing at my mobile and other PCs connected with the same connection.
Detailed information about the real cause and solution (preferably for both Ubuntu & Win10) will be highly appreciable.

The reason for DNS_PROBE_FINISHED_NXDOMAIN is typically due to a misconfiguration or problem with your DNS. DNS is short for Domain Name System, which helps direct traffic on the internet by connecting domain names with actual web servers.
Normally, this error occurs because a problem with the default DNS server that your computer or device is using. You can easily fix it by changing your default DNS server to other DNS services like Google's DNS, OpenDNS, or maybe one of these services. However, sometimes this error might be created by other causes.
For Ubuntu
These errors indicate that there is some problem with DNS.
check cat /etc/resolv.conf for your DNS settings.
And add following name server in /etc/resolv.conf for temporary or in /etc/resolvconf/resolv.conf.d/head for permanent
nameserver 8.8.8.8 nameserver 8.8.4.4
resolv.conf
sudo gedit /etc/resolv.conf resolv.conf Note: If you add name server only /etc/resolv.conf then when computer is restarted then /etc/resolv.conf is in previous stage.
So, to store these nameservers permanently, use following method :
sudo gedit /etc/resolvconf/resolv.conf.d/head /etc/resolvconf/resolv.conf.d/head
Re-connect internet connection
