Hi, I'm running Jenkins LTS (1.480.3) and after upgrading the plugins today Jenkins has stopped downloading the changes from my git server. It seems that jenkins is not accepting the self-signed certificate from the server any more. Any ideas on how to resolve this? I've tried to downgrade the plugin back to version 1.2.0 but nothing has changed. Maybe some dependency has been updated and downgrading the plugin is not sufficient to revert to the previous situation?
Thank you in advance, Aldo here is the stacktrace: Building remotely on Montavista in workspace /mnt/montavista/hudson/workspace/Megapixel_04.07.00 Checkout:Megapixel_04.07.00 / /mnt/montavista/hudson/workspace/Megapixel_04.07.00 - hudson.remoting.Channel@61df092e:Montavista Using strategy: Default Last Built Revision: Revision bd975b4d348b588ce3862f91dcd37e109193e799 (origin/04.07.00) Cloning the remote Git repository Cloning repository https://git.example.com/megapixel/my_build_tools.git git --version git version 1.7.2.3 ERROR: Problem fetching from origin / origin - could be unavailable.
