[stunnel-users] Problem with 5.40 and Peer suddenly disconnected

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.



client  = yes

accept  =

connect = xx.xx.web.com:443

sslVersion = TLSv1


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

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

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

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.
