I'm running  stunnel version 4.2  on Windows XP
I can access a lot of websites,  example  https://servicios.afip.gov.ar/tramites_con_clave_fiscal/misAportes/images/top.gif
but CAN'T access  https://apwebserver.rentasgcba.gov.ar/ablpatib_ssl/images/Actitud_BsAs_negro.gif
 
apparently a response never arrives to my PC
 
my conf file is
cert = stunnel.pem
; Some performance tunings
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
 
; Some debugging stuff useful for troubleshooting
debug = 7
; Use it for client mode
client = yes
 
; Service-level configuration
 
[https1]
client = yes
accept  = 6001
connect = servicios.afip.gov.ar:443
TIMEOUTclose = 0
