I have downloaded the remote certificates, and configured stunnel:

client = no accept = 127.0.0.1:9400 connect = 192.111.85.171:9400 cert = C:\Certificates\gain-futures-chain.pem verifyChain = yes verifyPeer = yes checkHost = 192.111.85.171 checkIP = api.gainfutures.com sslVersion = TLSv1.1 options = NO_SSLv2 options = NO_SSLv3 OCSPaia = yes

This results in the failure to initialize the tLS context:

This is the best I can gather regarding getting verification of the REMOTE certificate. The problem is that I am unable to connect if I cannot verify their certificate - they are not looking at my certificate. Any help would be appreciated. Thank you! -William Wood
