This is the second time I am having these problems, the last time it happened it was solved on the next day without doing anything.
What happens: I can log in to cockpit, the overview page is displayed with the four sections “Health”, “Usage”, “System information”, “Configuration” (might not be the exact names in English as I am translating from French), but Health is empty, CPU is 0, memory is zero, no ID, no on time, only system time is shown.
“Journal”, “Storage”, “Network”, “Services” show “loading” with a wheel forever. “Accounts” shows a blank page, “Applications” a smaller wheel forever, “Software updates” shows “Checking software status” and “Loading available updates, please wait” with a wheel forever.
“sudo systemctl restart cockpit” does not change anything .
