Why do I get this, dns_probe_finished_nxdomain

[bangers 69]

This means I cannot load any pages in my browser, I use a Huawei media pad M3, this happens often and goes away after a few days which is annoying.

Any suggestions please, thanks...

You get this error because the DNS server being used by your phone cannot convert your requested website server into an IP address.

Are you usually at home when this error occurs? Or other place where this error is always happening?
If you have control over the wifi router, you might try restarting it.

Just out of curiosity, is this error happening for random sites or always the same ones?
If same ones, which ones?

Some ideas for working around it are here, but not all apply to your phone:

I've installed "avg" and looks like the problem has gone, it came randomly and all websites wouldn't load. Thanks for your help....
