Hi
I am completly new in the ssl world : I am trying to compile wolfssl on raspberry pi, in order to use it with WifiDog.
I had an error with Wifidog, so I decide first to try to contact my server with the client app (in ./example/client)
I have followed some explanation on the forum, and I compile wolfssl with this parameters :
./configure --enable-opensslextra --enable-ecc --enable-supportedcurves --enable-debug --enable-psk --enable-aesccm --enable-debug --enable-aesgcm C_EXTRA_FLAGS="-DWOLFSSL_STATIC_RSA"When I run
./examples/client/client -h yahoo.com -p 443 -d -g it seems to work
But when I do it on my server I have this error :
connect state: CLIENT_HELLO_SENT
Embed receive connection closed
wolfSSL error occurred, error = 308 line:8672 file:src/ssl.c
wolfSSL Entering SSL_get_error
wolfSSL Leaving SSL_get_error, return -308
wolfSSL Entering ERR_error_string
wolfSSL_connect error -308, error state on socket
wolfSSL Entering SSL_freeI have run nmap on my server and I have this result :
PORT STATE SERVICE

|_ least strength: CI am trying to make it works since hours, but no success, some help would be very welcome
