I upgraded below listed plug-in's and that broke all my build jobs which are basically ansible playbooks in the back end with below error.

So at this point jenkins is not useful at all, I need some help in this regard, i'm not good at jenkins so don't know what to do and how to troubleshoot this issue. 

Error:

"
fatal: [host_name]: UNREACHABLE! => changed=false msg: 'Invalid/incorrect password: Permission denied, please try again.' unreachable: true
"
