After upgrading to 2.73.1, attempts to use Invoke-WebRequest (Windows only) to download from the Jenkins server (basically any request...but in this case it was downloading the slave.jar file) always throw:
The request was aborted: Could not create SSL/TLS secure channel.
This server has https enabled, with http redirecting to https via nginx. Nothing else changed except the upgrade from 2.60.3.
Now, this is quite possible a server configuration error, but I'm looking for some info on what might have caused the regression.
Connections of nodes via SSH, as well as curl on non-Windows platforms seem to be fine. Running inside the browser on Windows seems to be fine too.
Anything in either nginx or Jenkins logs? What URL are you requesting? Etc., this bug report is pretty anemic.
