well if the remote side is also your code, you could try debugging/finding why it closed the connection. you could also try setting the info callback to see what is happening inside the SSL connection (SSL_CTX_set_info_callback()). >> >> Hi, >> >> Arun Singarajipura wrote: >>> Hi All, >>> >>> we are working on client - server architecture.
