No response when git pull / fetch

I am unable to get any response by when i fetch or pull.
I aware that bitbucket is depreciating tls1 and 1.1, I did a check before dec 1 that my server supports tls1.2 (https://bitbucket.org/blog/deprecating-tlsv1-tlsv1-1-2018-12-01) and had a successful pull on dec 13, but now it doesn't gives any response when i do git fetch or pull. I used ssh to clone the repo.

When I run GIT_CURL_VERBOSE=1 git ls-remote https://bitbucket.org/ I get the following response:

• Couldn't find host bitbucket.org in the .netrc file; using defaults
• About to connect() to bitbucket.org port 443 (#0)

fatal: HTTP request failed

My server details are:
CentOS 6.10
Git 1.7.1
NSS 3.36.0
OpenSSL 1.1.0
Please let me know if there is any other info needed.

Any idea what is going on here?
