Hi  
When I “download” the reg-client and run locally. The reg-client app can’t discover devices.

hi Kamiri, Request you to check in master.ca\_cert\_store table whether Mosip signed Certificate for this device, PMS & ROOT Certificates are present. Partner Domain should be “DEVICE”. Incase Certificate not present Request you to copy the same from keymgr.ca\_cert\_Store table.
