Andreas Peters commented on MESOS-10218:
----------------------------------------
I could only reproduce the failure in my test mesos env when I remove the SSL
certificate. I'm sorry. :-( But we also use CentOS so I have no idea if there
is sth special with the ubuntu version. Maybe you can go into the slack channel
to ask someone else.

> 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_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
