Github unable to access SSL connect error

Question

I have been using git lots for the last few months. git push worked 12 hours ago now all attempts generate errors, with verbose it produces this:

GIT_CURL_VERBOSE=1 git push
* Couldn't find host github.com in the .netrc file; using defaults
* About to connect() to github.com port 443 (#0)
* Trying 192.30.253.112... * Connected to github.com (192.30.253.112) port 443 (#0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
*   CAfile: /etc/pki/tls/certs/ca-bundle.crt
   CApath: none
* NSS error -12190
* Expire cleared
* Closing connection #0
fatal: unable to access 'https://github.com/waveney/wmff/': SSL connect error

Any bright ideas? No changes to server from when it worked to now, restart made no difference

Answer 1

I was having the same problem on various CentOS 6 VM's and it turned out to be an issue with stale curl and nss libraries (thanks to this thread for pointing me in the right direction: cURL SSL connect error 35 with NSS error -5961).

The fix that worked for me is just:

yum update -y nss curl libcurl
