Hi,
Try the following:
1) Stop the Diagnostics agent.
2) Run the smdsetup script as described in note 1907909, and point to the JAVA SCS MS:
smdsetup managingconf hostname"sapms://10.26.91.29" port:"8102"
(preferably, use the FQDN and make sure that a Telnet from the managed machine can reach the solman in this port)
3) Restart the Diagnostics agent.
If it still does not work, check the role type as described in KBA 1963017.
If still you're having errors, check that the "TrustedP4Port" property is correct set in the Java NWA. This is done as described in KBA 2013578.
As of SAP Solution Manager 7.10 SP14 the TrustedP4Port and TrustedP4SPort can be easialy enabled in step 'Set Authentication Policy for Agents' in the System Preparation (SOLMAN_SETUP). NOTE: After enable the ports using the SOLMAN_SETUP, step 'Set Authentication Policy for Agents' the Solution Manager JAVA stack must be restarted.
For prior releases the steps to configure the TrustedP4Port or TrustedP4SPort ports are:
1) Go to "SAP NetWeaver Administrator" (/nwa) page of the Solution Manager Java stack.
2) Go to 'Configuration'
3) Go to 'System Properties'
4) Expand each instance entry (named like "Instance IDXXXXXXXXXX").
5) Select tab section "Services"
6) Search for service "security"
7) In the 'Properties' table find the "TrustedP4Port" property.
8) Provide the P4 port number to the TrustedP4Port of the server node.
9) In the 'Properties' table find the "TrustedP4SPort" property.
10) Provide the P4S port number to the TrustedP4SPort of the server node.
11) Repeat the steps 4 to 8 for every "ServerX IDXXXXXXXXXX" of every instance.
This KBA also describes an issue related to connecting the agents with certificate method.

Daniel.
