i/o timeout whilst fetch [Duplicated from exercism.io repo #3358]

[alex-bender]

During fetch I got this error:

$ exercism fetch c   
2017/01/25 17:41:03 Get http://x.exercism.io/v2/exercises/c?key=REDACTED: dial tcp: lookup x.exercism.io on 217.20.184.1:53: dial udp 217.20.184.1:53: i/o timeout

Would be better to have well described reason of this error;
Not sure if it is issue, or if it is already opened.

$ exercism --version
exercism version 2.3.0
$ uname -a
Linux bender 3.16.0-4-amd64 #1 SMP Debian 3.16.36-1+deb8u1 (2016-09-03) x86_64 GNU/Linux

Thanks @alex-bender, I'm open to this. Especially if we can also suggest what people might try.

[alex-bender]

@kytrinyx As far as I understand it is DNS issue (port 53), isnt'it?

[kytrinyx]

Weird, you're right. I'm pretty terrible at debugging DNS issues... why port 53? The website runs on port 80.

@alex-bender Try modifying /etc/resolv.conf file with below name server and fetch
nameserver 8.8.8.8
It worked for me like charm

@kishorekumar522 Thanks, but in my case it works with and without 8.8.8.8
