Re: [mosquitto-dev] Error - Unknown client certificate type

["Bradley, Dwayne" <Dwayne.Bradley@xxxxxxxxxxxxxxx>]

I'm using the latest Paho Java client library, 1.0.2.

I'll check on the openssl command and see what that yields as well.  Hopefully that can point me in the right direction.

Thanks,
Dwayne

Hi Dwayne,

Is this your client that is producing the unknown client certificate type error? If so, what client library is it using?

A good place to start with TLS errors is the openssl client. Try:

openssl s_client -connect host:port -CAfile ca.crt -cert client.crt -key client.key

Cheers,

Roger
