Hello all,

Getting a tsNet error, both from the IDE and a standalone. I have a patent 
searching and downloading app that had some link rot issues. Finally fixed 
everything. Seemed to be working fine for USPTO, European Patent Office  and 
World Intellectual Property Office. I put off launching this new version 
(Patent Grabber 6.5) for a few weeks. I don’t understand what has happened in 
the meantime, but the US patent searching keeps returning a tsNet error in the 
“result":

        tsneterr: (56) SSLRead() return error -9806

The URL was:

        
https://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2Fsearch-adv.htm&r=0&p=1&f=S&l=50&Query=(pokras)&d=pall

which works fine when pasted in Safari or Chrome on my MacBook Pro Retina 
running High Sierra 10.13.6.

I recently learned of the tsNet debugger that someone (Charles Warwick?) had so 
thoughtfully created, and tried it. Below are two runs that I made, and since I 
can’t make heads nor tails of them, I hope that someone on the list can 
understand what is going on (I also tried tsNetVerifySSLPeer, both true and 
false, but got the same tsNet error). Any help would be greatly appreciated. 
Thanks!
