I have this same problem with EveryStep v4.0.6114.8857
on MS Windows v10 Pro enUS (build 14393-rs1_release-inmarket.161208-2252).
I managed to create a script and tested it inside the Scripting Tool
about one month ago. But never could run it inside the Player,
even after 3 complete re-installations.
The thing is, there’s no proxy or access problems, every check I do
(default using http://cnn.com and other sites) is OK, except for the URL
I’m trying to test (public access to one of our services on AWS):

Making SV request to https://sinergie.misy.eu/
Status: OK.

Making UV request to https://sinergie.misy.eu/
Status: Error.
The underlying connection was closed: An unexpected error occurred on a send.


What is this UV (?) request and what are the differences for a SV (?) one?
This error is “Type 205 – error code 12500 – An unexpected error occurred on a send”
(https://www.dotcom-monitor.com/wiki/alerts/error-codes). What does this mean exactly?
Our servers never do that on every browser I have in this machine (all the must
recent versions of MS Edge, MS IE v11, Mozilla Firefox (v50.1.0) and Google Chrome (v55.0.2883.87 m)).
