Why GIT Plugin in Jenkins is not able to connect to the GIT Repository?

Question

I am trying to pull the code form GIT using GIT Plugin Jenkins and the job is running on a slave machine.

MASTER system has http_proxy=mycom.domain.com:80

and in SLAVE system there is no http_proxy defined.

Whenever I am doing git clone locally in the SLAVE machine it works perfectly, however from Jenkins I haven't been successful.

It is throwing the following error:

Building remotely on SLAVE in workspace /data/test

 > /usr/bin/git rev-parse --is-inside-work-tree # timeout=10

Fetching changes from the remote Git repository

 > /usr/bin/git config remote.origin.url https://github.domain.com/Project-Digital/Project-eCommerce.git # timeout=10

Is it because the MASTER system trying to set http proxy which is not present in the SLAVE system?

If yes, how to prevent it?

Or, is there something else I am missing?

Not sure about this but i think its a proxy issue. So, just add the GIT URL to No Proxy Host section (Manage Jenkins -> Manage Plugins -> Advanced -> HTTP Proxy Configuration -> Added GIT URL in No Proxy Host field) in Jenkins and now it is working fine.
