git fetch error when fetching on jenkins script

Question

I'm having issue fetching code from HTTPS gitlab using jenkins pipeline, it's giving me error timeout as below. I don't have any issue fetching repo from HTTP gitlab server.

NOTE:

1. My jenkins server and HTTPS gitlab server are in the internal network, and I have cleared the network firewall.
2. No issue accessing the HTTPS gitlab webpage via browser.
3. No issue when fetching repo from my HTTP gitlab server.
4. My HTTPS gitlab server is using self signed cert.

Below are the error messages in jenkins console output, I have masked the git repo URL for confidential purpose.
