[stunnel-users] Configuring Stunnel to work between client and server - possible certificate issue

I see, I have a keystore file for the server, can it be set as KEY ? can I convert keystore to PEM?
Additionally, I've thought about configuring Stunnel in client mode.
Here is the configuration:
client = yes
accept = 127.0.0.1:8449
connect = 192.168.220.72:444
verify = 2
CAfile = server.pem
In this case, my application appears to successfully connect to Stunnel & send messages.
But when it tries to access it in order to collect messages, it fails:
(App in C++)
Error: socketReceive data failed (Requested: 4 bytes, Cur chunk size: 4 bytes. Progress: Got: 0 bytes, Left: 4 bytes): System Err: An unknown error occurred while accessing an unnamed file.
Thank you for your assistance.

Please reply to the list, so others are able to comment too.
I don't know the 'default certificate provided by Stunnel'. I expect it to be depending on the distribution.
However, if there are "BEGIN/END CERTIFICATE" lines in your file, but no "BEGIN/END RSA PRIVATE KEY", then the file is in PEM format, but the key is missing. Maybe you have separate files for private key and certificate. If this is the case, you may either concatenate key and certificate to a single file or specify both files in the stunnel
