Windows Pro -- can't reach Insider program, Enterprise and Workstation editions --OK build 26090.112

Hi there
updating 3 Windows versions with the latest canary build (there's a cumulative update from 26090.1 to .112) - fine on Windows Enterprise and Windows for workstations -- but in Windows 11 pro I get message -- unable to reach the windows insider servers !!!!!

What gives!!! surely the cumulative update is common here !!! -- or at least just return back no update if there isn't one for that particular edition.

Both Windows enterprise and Windows for workstations show build as 26090.112 and no problem accessing the Windows insider program.

(running on a physical Windows laptop -- not a VM, nor a "jury rigged one" to bypass ineligible hardware. Bog standard installs).

Cheers
