Let's start with the obvious, just to make 100% sure we're really having an
issue here.

You are 100% sure sizeof(wh)==10? Do you check to be sure nread==10 after
this block? If it isn't, and you move on to the next chunk, you'll cause
exactly this problem. Is SSL_MODE_AUTO_RETRY set? (I'm assuming the
intention is for SSL_read to block until the session can be established
right?)

This looks fine, though it's terribly inefficient. (I hope you don't
particularly care about performance.)
