I had a technical problem that forced me to change my jenkins master computer. I took the hard disk and moved it to a new computer, but now the IP of the master computer changed.
The master jenkins works but the slave nodes are marked as offline, and when I try to create new nodes the installation fails on the node pc. I noticed that the error I get when creating new nodes is connection time out, and i see the old IP.
How can I fix this?
I found the solution, I will post it in case anyone else will have this problem:
