# See question on StackOwerflow "QSslSocket error when SSL is NOT used" (http://stackoverflow.com/a/31277055/3045403)
# Copy of answer:
# We occasionally had customers getting very similar warning messages but the software was also crashing.
# We determined it was because, although we weren't using SSL either, the program found a copy of OpenSSL on the
# customer's computer and tried interfacing with it. The version it found was too old though (from Qt 5.2 onwards v1.0.0
# or later is required).
#
# Our solution was to distribute the OpenSSL DLLs along with our application (~1.65 MB). The alternative is to compile
# Qt from scratch without OpenSSL support.
