Re: Port not reachable while creating a slave agent in windows for a linux master

Have the same problem. If I try connect the same agent to another Jenkins server on Windows 10, everything works. Both servers have same version of Jenkins (2.190.1), approximately same set of plugins. Even tried to use static port and explicitly whitelist it on CentOS, did not help.

I'm seeing this too. The Windows 10 1903 agent is able to connect to a macOS server without problems, but fails to connect to a Fedora server.

Re: Port not reachable while creating a slave agent in windows for a linux master

Managed to dodge this one. You just need to login to the centos server and add a firewall rule for that port: {{ firewall-cmd --permanent --add-port=37583/tcp}} {{firewall-cmd --reload}}
