ZCM 11.4.3 VA. Not sure, but at some point I noticed subscription service didn't poll anymore. ZCC - Subscription Service Settings poll date not renewed. Well, on Patch Management page in ZCC I saw error "Failed to download subscription" etc. Tried manual renew (Update now) ... nothing. Tried Reset Subscription Service ... same. Finally missed third line in Patch Management Subscription Service History at all (about Subscription). Haven't tried restart server, maybe there is a option to start this service without. Licensing should be ok.
Any ideas?
More thanks, Alar.
