SOLUTION: Delete /var/cache/bind/managed-keys.bind and /var/cache/bind/managed-keys.bind.jnl, and restart bind with systemctl restart bind9. These two files will get auto-created with the missing key within KEYDATA.

Did you check if you have a default route? I think it's missing. nabil@LAPTOP:~$ ip route default via 172.30.80.1 dev eth0 -Default route 172.17.0.0/16 dev docker0 proto kernel scope link src 172.17.0.1 linkdown 172.30.80.0/20 dev eth0 proto kernel scope link src 172.30.85.180 Can you check on the PC1 and on the router as well. On the router Netplan config, ...

I have encountered exactly the same issue while configuring systemd-resolved and dnsmasq. For your question 1, I am not able to find out why systemd-resolved query for AAAA record repeatedly while there is no reply from dnsmasq. For question 2, the dnsmasq is not correctly configured to add a record for foo.bar. You only add an A record for this domain name, ...

Thanks to the comments, I found out that the issue was related to an incorrect DNS Server configuration, which I could check by temporarily changing the /etc/resolv.conf file. I tested this on Ubuntu Impish (21.10) but I suppose that applies other Ubuntu releases too. You can check your real ISP DNS Server on the router page to be sure (i.e. for me it's ...

I am having the same issue. I have tried everything from all answers and none of these work for me. I am working right now on something which requires a lot of DNS updates and this completely blocks my work all the time. I have to go and look at the site on my phone / ipad to see if it is really working. Is there any other possible solution ?

I just found another method that works for me: Enable Connectivity Checking in Settings. This will pull up the captive portal at Starbucks. (Read this somewhere on SO but now can't find the page anymore)

I always had some Internet interruption when using FortiClient VPN. A solution that always works for me : Go to your wifi settings Click on the settings of your connection Click on 'Forget the connection' Then all I have to do is reconnect to this network (and type the password, hum...) and Internet is back

OK, so I faced the same problem. My VPN was connected then I pressed CTRL + ALT + F11 then It went into some kind of sleep mode, and then I had to restart my laptop after long pressing power button. So then my internet and Gs connect stopped working, I uninstalled proton vpn but the problem still persisted, So what I did was just reinstalled protonvpn but ...

Multiple services including netplan, network-manager, and dhcpd all need to make changes to resolv.conf to reflect current network configuration. Typically in an ubuntu system, the systemd-resolve and resolvconf services try to juggle this, and you will find that the file /etc/resolv.conf is actually a symlink to /var/run/resolvconf/resolv.conf. If you want ...

At reboot /etc/resolve.conf usually regenerated and can be rewritten / created on occasion by your DHCP or other services. You can try to disable getting dns-nameservers from your DHCP server if it's the case. dhclient usually overcomes most resolvconf files. So updating your /etc/dhcp/dhclient.conf and /etc/network/interfaces files can work. Answers and ...
