I had this today. Searched high and low. In the end, I turned off WiFi and turned it back on. Synched immediately. Hope that helps.

Hi, thanks for the reply. The problem was caused by the installed firewall, which was somehow reset during the OS update. It's fine now. Thanks again, Zdenek.

I may not be able to help, but it would be good to know

How long has it been?
Do you have Desktop and Documents included in iCloud Drive?
Do you have "Optimize Storage" turned on?
How much free storage do you have on your Mac? System Settings>General>Storage. Is at least 10% free?

I don't have Desktop and Documents included in iCloud Drive. I have 125 GB free out of 200 GB on iCloud. I have 185 GB free on the system drive.

Before the last update to version 26.0.1 everything worked for many years...
