Hi, everyone.  

I upgraded my server app to Boost 1.79.0 and tried running it, but there are issues: 

1. I renewed my Let's Encrypt certs, but when I try to check them, I see it's only sending one cert out of a chain of three.  And I'm loading the certs and the RSA private key using the SSL context methods to load the cert chain and key from files, too.
2. The read operation on line 640 in the do_session function in currency_converter.cpp gave a "bad method" error before, but mostly gives "the connection was forcibly closed by the remote host" error.
