[stunnel-users] problem accesing a https site as a Windows version client

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/to... but CAN'T access https://apwebserver.rentasgcba.gov.ar/ablpatib_ssl/images/Actitud_BsAs_negro...

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

[https] client = yes accept = 6002 connect = apwebserver.rentasgcba.gov.ar:443 TIMEOUTclose = 5
