Problem to add witches to SPM

Problem to add witches to SPM

Hi Team,

I tried to add a cisco switch to OpUtils Switch Port Mapper to monitor its port. I go to Network tab>IP management> switch port mapper and click on "add switch" button to add it manually or through discovery using SNMP v1/v2 credential. It takes a long time and shows a message " adding please wait", but nothing happens. The switch already exists in inventory, but I cannot add it in SPM to see its port view. 

What is the problem and how can it be solved?

Thanks.
