SSL Error Certificate subject name does not match target host for github.com

Question

I'm trying to access github's repositories using git fetch but I'm getting this error:

error: SSL: certificate subject name (*.opendns.com) does not match target host name 'github.com' while accessing https://github.com/<repo name>

This happened earlier this afternoon very suddenly, and it didn't go away. I thought it might be a problem with Github rejecting older versions of OpenSSL.

I am running Ubuntu 11.04 (Natty Narwhal), Git 1.7.4.1, and openssl version -a gives this:

OpenSSL 0.9.8o 01 Jun 2010
built on: Tue May 22 23:20:32 UTC 2012
platform: debian-i386
options:  bn(64,32) md2(int) rc4(idx,int) des(ptr,risc1,16,long) blowfish(idx)

DHAVE_DLFCN_H -DL_ENDIAN -DTERMIO -O3 -Wa,--noexecstack -g -Wall
OPENSSLDIR: "/usr/lib/ssl"

Any help would be greatly appreciated!

UPDATE 5/1/2014:

Ended up updating Ubuntu to solve this issue. Read somewhere that that is the most secure solution since both my local machine and Github's servers will be as up-to-date with each other as possible.

Answer 1

You need to modify your /etc/resolv.conf file and remove/replace any reference to OpenDNS servers. This is what I did to my /etc/resolv.conf

In /etc/resolv.conf, replace

#OpenDNS
nameserver 208.67.222.222
nameserver 208.67.220.220

to

#Google
nameserver 8.8.8.8
nameserver 8.8.4.4

Let me know if this resolve your SSL issue.
