Our server was running Jenkins 1.624 for a year without any problem. But one day all job to remote servers (git and webdeploy) stopped to work and all job are finishing in timeout (10 min).
Our jenkins service was running with the local system account.
We already verified network but everything was fine.
A restart of the service or the server could not solved the issue.
We needed to change for another service account in order to make everything work.
But few days later the issue is back. We already try to configure the jenkins account with local and active directory account but few days later the issue is back.

As the jenkins version was old and not stable we made a minor upgrade and also we installed on the same server in parallel the latest version (2.7.3).

The issue still occured with theses version. Even sometime the service account sthat we are creating dont solve the issue. But at least it start the jenkins service everytime.

In order to make jobs running fine we need to try different service account until finding one working.

Nothing was installed or update when the issue was reported for the first time.

Did anyone encounter this major issue ?
