SPC Integration error with SEPM 12.1.5

Hello all, Prior to upgrading to SEPM 12.1.5 one of my customer was running SPC in their envoirement that was managing 18 diffrent SEPM's in diffrent regions. Now when they upgraded SEPM's to 12.1.5 then after the upgrade the information from SEPM's are not being displayed in the SPC console and dashobards are not working.

I have already removed all the SEPM's from SPC and re-added them but the same problem persists. Is there any compatibility issue between SEPM 12.1.5 and SPC 3.0 Enterprise? would appreciste if any 1 can shed some light on it. Thanks
