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. Brian
