Deployment Architecture

Why am I getting the following error from the Splunk deployment application and Splunk deployment server?

We are not able to connect to one of the application server. We are seeing the following error on the deployment server. We did modify an existing application, but it's not reflecting changes:

WARN HttpListener - Socket error from while idling: error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher

that's probably du to the default cipher list being more strict with newer versions.

if so look at known issues :
especially this one :
Older 6.0, 6.1, 6.2, 6.3 maintenance release versions unable to connect to 6.6.x and later via management port

This applies to License Master/Slave, Deployment Server/Client, Cluster Master/Peers, Search Head/Peers and affects Splunk 6.6.x and the following versions:

6.0.0 to 6.0.6
6.1.0 to 6.1.4
6.2.0 to 6.2.6
6.3.0 to 6.3.1

Upgrade your older instances to the latest maintenance releases or on your 6.6.x Splunk instances. Add the following stanza to server.conf:

sslVersions = *,-ssl2
sslVersionsForClient = *,-ssl2
cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH

We do have communications going on from other application servers. Only one application server is not sending data to Splunk. Our deployment server is 7.0 and splunk forwarder is 6.5 version. On which server do I need to apply this stanza update also can you please provide the path for it?

Make sure the sslconfigs under server.conf match both Deployment server and the client...
