None of our data center machines are able to connect so perhaps this is a firewall or NAT issue? Anyway here is the very un-descriptive error message:
**** SSL_connect: error:00000000:lib(0):func(0):reason(0) ---- Closing control socket `ls' at 0 [Delaying before reconnect: 18]
Further investigation reveals that this is probably due to a firewall issue, where the client may not be able to connect to the control channel due to the encryption.
Anyone have a workaround or solution to this problem?
