Jenkins not able to fetch code from remote git

My jenkins build is suddenly not working now.The error is as follows:-

Fetching changes from the remote Git repository
 > git config remote.origin.url <url> # timeout=10
ERROR: Error fetching remote repo 'origin'

I am not able to figure out the root cause. I have checked the permission and ownership for jenkins home folder which is /var/lib/jenkins:- drwxrwxrwx 17 jenkins jenkins 4096 Jun 25 04:30 jenkins

Permission and ownership of .git folder inside workspace folder of jenkins is:- drwxrwxrwx 8 jenkins jenkins 4096 Jun 30 21:51 .git

Please guide me fix the problem.

Solution 1:

I was seeing the same issue, but disk space and VM memory were not the problem. What fixed it for me was making the job re-clone on build:

Go to the job's "Configure" page
Under Source Code Management → Git → Additional Behaviors, add a behavior "Wipe out repository & force clone"
Save
Build

Solution 2:

Experienced it when Jenkins VM was running out of disk space. Cleaned it up, don't see this problem anymore.

Solution 3:

Try clearing out the workspace files and rebuilding.

Solution 4:

In my case, fetching/downloading the remote code was quite slow and was aborted due to a timeout. So I increased the "Timeout (in minutes) for clone and fetch operations" to 20 minutes.

enter image description here

Solution 5:

In my case, found that my infrastructure team member changed the ownership of the workspace. After changing folder ownership (in my case it jenkins:apache) its start working.
