After updating to stunnel 5.40 on x86-pc-msvc-1500 platform, I am getting a Peer suddenly disconnected each time I post data to a particular url.

[VISION_WEB]

client = yes

accept = 127.0.0.1:1935

connect = xx.xx.web.com:443

sslVersion = TLSv1

2017.02.07 16:30:08 LOG5[160]: Service [XX_WEB] accepted connection from 192.168.100.21:53507

2017.02.07 16:30:08 LOG5[160]: s_connect: connected 11.11.111.36:443

2017.02.07 16:30:08 LOG5[160]: Service [XX_WEB] connected remote server from 192.168.100.21:53508

2017.02.07 16:30:08 LOG3[160]: SSL_connect: Peer suddenly disconnected

2017.02.07 16:30:08 LOG5[160]: Connection reset: 0 byte(s) sent to TLS, 0 byte(s) sent to socket

This is a production issue and is causing a lot of problems for a lot of people and I need to do something quickly.

Is it possible to download stunnel 5.37 installed to see if going back to this version will fix this issue? Where is it?

Or does anyone possibly know why this might be happening? Thank you for your help.
