applied simple test-case (edited in the message above). Thanks for care.

Shocked but I've got our UPP's forum link to this page (html) OK - to here " https://www.ultimatepp.org/forums/index.php?t=msg&goto=6 0885&#msg_60885" with code above -- perhaps the problem is not in SSL-package, but in some additional security-measures to my needed link (mentioned above) ??
p.s.
csv with temperatures " https://raw.githubusercontent.com/elmoallistair/datacamp/ref s/heads/master/data-manipulation-with-pandas/datasets/temper atures.csv" - is also OK. Perhaps really I should find the problem cause in something else [if nobody else can load my cmegroup.com link above - still being loaded ok in any Windows' browser], problem not in UPP. I like UPP Smile . Thanks
