I switched the Jenkins to using https on port 8080 . After a restart of the Jenkins,the slaves cannot reconnect.

I changed only Jenkins location from Configure System -> Jenkins Location -> Jenkins URL to https://localhost:8080

Know someone who can answer?

    Why do your posts all contain a superfluous link to opstrainerz.com ? Maybe you should be asking them for help and not S/O if their training is not clear? Are you misleadingly trying to drive traffic to the site? Do you have an association to the site?

It depends on how you connect you slaves via ssh or jnlp, in any case: check if you are able to connect that slave and try telnet it.
