Hello,
Could you please check if there is 2 are domains assigned in the SEPM?
SEPM >> Admin >> Domain
By default, there is 1 domain "Default"
If you see 2 domains, please highlight the other domain and click on "Administer Domain" and then click on Clients tab to see the client reporting.
If you haven't created this domain, you may consider this domain to be marked under deletion.
Regards,
