--------------------------------------------
[~apeters] I ran the curl from the slave itself.
I installed it from the repo, deb package.
This is the error I get if I set LIBPROCESS_SSL_SUPPORT_DOWNGRADE=false

I don't see this error if I set LIBPROCESS_SSL_SUPPORT_DOWNGRADE=true

> Priority: Major
>
> Mesos agent fails to connect to the master after setting the following
> variables:
> LIBPROCESS_SSL_ENABLED=1
> LIBPROCESS_SSL_KEY_FILE=/etc/mesos/conf/ssl/server.key
> LIBPROCESS_SSL_CERT_FILE=/etc/mesos/conf/ssl/server.pem
> LIBPROCESS_SSL_REQUIRE_CERT=false

> LIBPROCESS_SSL_VERIFY_CERT=false
> LIBPROCESS_SSL_CA_DIR=/etc/mesos/conf/ssl
> LIBPROCESS_SSL_CA_FILE=/etc/mesos/conf/ssl/ca.pem
> LIBPROCESS_SSL_SUPPORT_DOWNGRADE=false
> LIBPROCESS_SSL_VERIFY_IPADD=false
> #LIBPROCESS_SSL_ENABLE_TLS_V1_2=true
> Error in logs:
> Failed to accept socket: Failed accept: connection error: error:1407609C:SSL
> routines:SSL23_GET_CLIENT_HELLO:http request
> Connectivity works after setting:
> LIBPROCESS_SSL_SUPPORT_DOWNGRADE=true
> But then the sandbox fails to open in the web UI:
> Potential reasons:
> * The agent is not accessible
> * The agent timed out or went offline
> With the following error in the logs:
> Failed to recv on socket 38 to peer 'unknown': Failed recv, connection error:
> Connection reset by peer
