How to get Jenkins to connect to git repository

Question

I'm having trouble getting Jenkins to recognize my git repo. The screenshot is below. I was told using git clone https://blah/blah.git will clone the repo as read-only w/o needing credentials or keys. I want to just pull the code and build it.

The funny thing is when I execute the same command from the command line, it works and files get pulled down from the repo.

export GIT_SSL_NO_VERIFY=true
git clone https://blah.com:8443/blah.git

When I enter the url and environment variable in Jenkins, it's says it can't connect to the repository. Does anyone know what I might need to do to get it to work? Thanks in advance for your help.

UPDATE/CLARIFICATION: The Jenkins install is under a service account, not related to any user within the company.

UPDATE#2: Here's the console output. I've sanitized it a little so i apologize if i missed something.

Thanks for everyone's suggestions, comments, and help. I think this is a plugin issue. Someone else experienced the same thing I did (original post here). If I run this command from the command line or if I enter the command in Jenkins as Build>Execute shell>Command, it works fine.

I have Git Client plugin = 1.4.3 and Git Plugin 1.5.0. I'll wait to see if a newer plugin fixes this.
