Some AI models could not be downloaded.

Since Saturday, November 14, Photoshop, Camera Raw and Lightroom Classic (Windows 11) show this message when loading AI tools:

“Some AI models could not be downloaded. Please try again later.”

Already tried without success (partly together with Adobe chat support):

• Signed out and back in to Creative Cloud
• Restarted the PC
• Reinstalled Creative Cloud
• Installed an older Photoshop version, then reinstalled
• No proxy configured
• hosts file is clean (no Adobe entries)
• Tested other DNS servers (1.1.1.1 / 8.8.8.8)
• Firewall and ad blockers disabled
• 149 GB free disk space, date and time are correct

Is there a known server-side issue, or a way to find out from the logs why the model download fails?

Thank you!
