Fatal unable to access ssl connect error appears under centos6.3

ssl certificate problems under centos6.3 cause git clone / curl github resources to fail 

  https://www.v2ex.com/t/434848

 is there any way to upgrade if you don"t want to upgrade? 


 what is given on the Internet is basically upgrading nss-related packages 


  yum update-y nss curl libcurl  


 but I still have no effect here
Curl golang github ssl-Certificate centos
Mar.14,2021

with this problem, using update did not take effect

but after testing, it seems that there is something wrong with the version of ssl

Test method: 

curl -v https://github.com

prompt 

* About to connect() to github.com port 443 (-sharp0)
*   Trying 192.30.253.112... connected
* Connected to github.com (192.30.253.112) port 443 (-sharp0)
* Initializing NSS with certpath: sql:/etc/pki/nssdb
*   CAfile: /etc/pki/tls/certs/ca-bundle.crt
  CApath: none
* NSS error -12190
* Closing connection -sharp0
* SSL connect error
curl: (35) SSL connect error

but 

curl -v --tlsv1 https://github.com

you can get the correct page response

git level 2.6 or above, you can specify the ssl version number. There are two ways

  1. export export GIT_SSL_VERSION=tlsv1
  2. git config http.sslVersion tlsv1

upgrade git > = 2.6 set ssl version, try it out

should it be possible to bypass ssl authentication directly?
