Maybe this unresolved issue is still there!? https://issues.jenkins-ci.org/browse/JENKINS-48850
From: jenkinsci-users@googlegroups.com <jenkinsci-users@googlegroups.com> On Behalf Of Jérôme Godbout Sent: September 1, 2020 2:12 PM To: jenkinsci-users@googlegroups.com Subject: RE: Windows client ssh connection error Did try without the firewall and it doesn’t work either, !?!? Anyone got an idea what it is actually doing that might not work?!? Both machine are on the same network, no ip conflict. If I delete the remoting.jar and the folders into c:\JenkinsSlave it get created again, so the connection is happening and it can transfer the file.

The log on the slave are empty (c:\JenkinsSlave\remoting). The error is a bit vague and I have no clue what is wrong. I can connect with ssh, I also did it on the master node to approve the address to ensure it was not an issue. Seem like the exchange stream are breaking down!?! what is going on?
