SSL ERROR

Hi together,

i have found a lot of SSL ERROR Messages in the cloudstack management-server.log like these: 
(AgentManager-SSLHandshakeHandler-1:null) (logid:) SSL error occurred while processing unwrap data: Unrecognized SSL message, plaintext connection?

Anyone has an idea how to fix it ?

Kind Regards 

Benjamin

Hi Benjamin,

I may be stating the obvious – but are you sure this isn’t just part of the session handling? The “plaintext connection?” statement would make me think this is indeed the case and the handshake continues successfully from that point onwards as plaintext.

Or – to put it differently – are you using SSL certs on your hypervisors?

If you have a monitoring script that if port 8250/tcp is open on the mgmt server that could be causing it as well, other possibilities include rogue clients/parties trying to access tcp port 8250.

Hi Bejamin,


On which CloudStack release/version are you getting this error? It's likely one or more CloudStack CPVM/SSVM/KVM agents are not able to perform a proper SSL handshake with the management server(s). If you have a monitoring script that if port 8250/tcp is open on the mgmt server that could be causing it as well, other possibilities include rogue clients/parties trying to access tcp port 8250.
