[Solved]Fail to access all the web page, DNS_PROBE_FINISHED_NXDOMAIN

Hi,

I encountered network issue these days, i can't visit all kinds of web page, the error is,

This site can’t be reached
www.baidu.com’s server IP address could not be found.
DNS_PROBE_FINISHED_NXDOMAIN

I can connect use ssh with ip address but not domain name:

➜ ~ ssh melu@lxplus6.cern.ch
ssh: Could not resolve hostname lxplus6.cern.ch: Name or service not known
➜ ~ ssh melu@188.184.91.243
Password:

so i guess the issue may from the DNS, the content of /etc/resolv.conf is:

# Generated by NetworkManager
nameserver 162.105.129.122
nameserver 162.105.129.102

as this is generated by NM automatically, i guess it should be fine. I disable ipv6 in Network->VPN->IPv6->IPv6 Method, but the problem is still there. I also tried with adding 'nameserver 8.8.8.8' to /etc/resolv.conf, but it didn't solve the issue.

i checked that the Firewalls is not active,

systemctl status iptables.service 
● iptables.service - IPv4 Packet Filtering Framework
   Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled; vendor preset: disabled)
   Active: inactive (dead)

Could you please help me to solve this issue, thanks in advance.
