Streaming Replication Log is puzzling me
You appear to have two separate problems an issue with OpenSSL renegotiation.

First - nope, I was wrong, see Daniel's answer.

Second, you're being bitten by an OpenSSL issue with renegotiations. Searching for the error message would've told you this. As noted in that bug report:


  Workaround is to set 'ssl_renegotiation_limit=0' in postgresql.conf


which asks PostgreSQL to tell OpenSSL to stop attempting renegotiations, since that version of OpenSSL has broken renegotiation support.
