Problem with Google search

[#1]

Intermittently for every search in Chrome, i get this

This site can’t be reached

Check if there is a typo in www.google.com.

when I do an nslookup on www.google.com i get-

$ nslookup www.google.com
;; connection timed out; no servers could be reached

At other times when search is working I get this-

$nslookup www.google.com
Server: 127.0.0.53
Address: 127.0.0.53#53

Non-authoritative answer:
Name: www.google.com
Address: 142.250.187.196
Name: www.google.com
Address: 2a00:1450:4009:815::2004

This happens both from my Ubuntu Desktop and my Android mobile. If I use a 4G connection on my mobile all is fine so looks like a problem with my plusnet connection.

Any help would be appriciated its been going on for weeks now.

What router are you using?
Also please set alternative DNS servers to test it’s just a DNS issue.

Thanks for the reply.

My router is a Draytek Vigor 2820

I've set my DNS to 8.8.8.8 and 8.8.4.4

it was just set to automatic.

Lets see if this helps.

Thanks
