I keep getting DNS_PROBE_FINISHED_BAD_CONFIG error. How can I fix this?

Question

I've seen this question and tried the answer at the bottom of the page yesterday and it seemed to work. But then I woke up today and had the same DNS_PROBE_FINISHED_BAD_CONFIG error for like over an hour. So then I tried that solution at the bottom again and it seems to have worked but just in case I created an account and am making this question. I also tried the answer with 26 likes but ran into a problem. I pasted sudo rm /etc/resolv.conf to my terminal and after typing in my password nothing happened.

EDIT: The error happened again as I was trying to post this. I am now using a wired connection.

When I pasted ls /run/resolvconf/interface/ in the terminal I got NetworkManager.

EDIT from comments: I have a modem from ubee, it's DDW365

Everything from "127.0.0.1 localhost" to "ff02::2 ip6-allrouters" was what was within my hosts file.

127.0.0.1   localhost

127.0.1.1   aaron-Aspire-One-721

#The following lines are desirable for IPv6 capable hosts

::1     ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

This is from my host.conf file:

 # The "order" line is only used by old versions of the C library.
    order hosts,bind
    multi on

None of my DNS match the DNS here.

Solution

Try

sudo dhclient -r interfacename
sudo dhclient interfacename

where interfacename is yours (mine is eth0)

This will release and renew your Ip address.

If this doesn't help, The COX DNS servers you are using may be overloaded. This is especially likely if this is an intermittent problem.

Google Public DNS operates recursive name servers for public use at the following IP addresses: 8.8.8.8 and 8.8.4.4 for IPv4 service, as well as 2001:4860:4860::8888 and 2001:4860:4860::8844, for IPv6 access. The addresses are mapped to the nearest operational server by anycast routing. I suggest you try those and see if you get better results.

I've found 8.8.8.8 to be very responsive. Open Network Connections and edit your entries as shown below. Then Click Save. This should resolve the issue.

It says Automatic as method. The Address box is also blanked out.

[BlackTunicLink]

And I have a hosts file and a host.conf file. So I misread when I said I had two earlier.

[BlackTunicLink]

I already have that stuff saved to my hosts file. I'll enter that command in the terminal.

[BlackTunicLink]

I did everthing you asked me.

[BlackTunicLink]

How do I find my network interface name? I just noticed that you edited your post. Also, this problem is intermittent. I've never had this happen before until now.

[Elder Geek]

nmcli device show will give details on both the wired and wireless and it will be clear which is which. See my answer in regards to intermittent DNS problems. (I.E. Change DNS settings)

[BlackTunicLink]

This is what I get when I type that. i.imgur.com/LTY1l0b.png I used the text with DDW365 in it but it was apparently too long.

[Elder Geek]

enp3s0 is your wired connection (not connected). wlp6s0 is your wireless connection (connected). I see you have not yet changed your DNS settings as I suggested in my answer. Please do so and let us know the results. Thank you.

[BlackTunicLink]

I changed my DNS settings. The problem kind of appears and disappears so it'll take a while for me to see if it's really been solved. Probably around half an hour. It usually occurs at least once in an hour.

[Elder Geek]

No worries. If it has an impact we know it's not your system that is the problem.

[BlackTunicLink]

The problem seems to have been solved. I haven't run into the error anymore. Thanks for all of your help.

[Elder Geek]

If my answer worked for you please accept it by clicking the checkmark so that others with the same issue will know that it's a working solution.

[BlackTunicLink]

Now I just got this error: DNS_PROBE_FINISHED_NO_INTERNET I had to disconnect and reconnect so it'll work again.

[Elder Geek]

You should contact your ISP and ask them why your service is intermittent. Further reading: usefulpcguide.com/17691/dns_probe_finished_no_internet

Oh yeah I forgot to tell you this. After putting sudo dhclient -r wlp6s0 into the terminal and then putting in sudo dhclient wlp6s0 nothing would happen for me. It would just go back to aaron@aaron-Aspire-One-721:~$.
