After the update on 9/21 all transaction on our site would yield the error:

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

Hoeever, according to shaaaaaaaaaaaaa.com our certs were fine. 

After some digging, our developers found the issue was our dated version of Ubuntu/OpenSSL kept us from updating to TSL 1.2. So, we began the full ugprade process and re-deployed the application on an upgraded VM.

Everything looks good, we're on the updated VM, but we are still getting the same SSL error. Any insight would be greatly appreciated.
