Thanks you Andreas Tscharner:
Is the TCP port on the master (Manage Jenkins -> Global Security ->
> Agents) set to static?
The option was disabled and I set it to auto.
After that I got a handshake error when starting (with java 1.8.0_152):

Or I receive a connection timeout error when starting (with java 1.8.0_171):

OpenJDK Runtime Environment (build 1.8.0_161-b14)

is used to run Jenkins on the server.
I tried different JREs on the agent machine because I found this
<https://support.cloudbees.com/hc/en-us/articles/115003785531-SSL-handshake-failures-due-to-incompatible-Cipher-Suite>
(even
if the server JRE isn't 162+).
You know what I missed this time?
Thanks a lot!
