The self signed certificate for firmware versions on various DMP systems expired on 24th February 2012 causing failure of communication between the DMM and DMP systems, leading to content not playing on schedule.
The self sign certificate expiration causes communication failure between the DMP and DMM systems. The DMP system shows status "down" in the DMM GUI. The customer might observe that the scheduled content may not play on the DMP system.
Starting 24th February 2012, the DMP and DMM system communication fails with DMP Manager UI and reports the "HTTP status: 500 Unknown Exception: peer not authenticated" error message. The DMP Manager UI reports DMP status as "down" and does not play the content as scheduled.
Cisco recommends that the customer apply the software fix to recover the self sign certificate expiration. Follow the steps outlined below:
Step 1: Log in to your Cisco.com account and then go to this software download URL:
Based on your DMP Software Release, go to All Release, then select '5' and the Release number.

Note: Release 188.8.131.52 does not have a Patch. The customer must use the Patch posted for Release 5.2.2.
