[stunnel-users] Stunnel 4.3 not forwarding to server socket

[Vladimir Stariradev]

Dear Stunnel users,

I'm running stunnel on my server which accepts connections from my
mobile phone emulator (j2me) like so: midlet app ->   port:5555 stunnel ->
port:6666 server. My midlet, which can be treated as a java app, uses
ssl://127.0.0.1:5555 to connect to stunnel. I can establish a connection
between the stunnel and the app because I can get information on the
certificate.

The problem is that when I send data from the midlet to the server, the
server doesn't accept it, nor does it signal that anything has been
received even when I have double-checked that the streams are setup.

I have pasted my config and log files below. Any suggestions are fully
appreciated.

Regards,
Vladimir
