Windows 10 DeliveryOptimization : FailurePeerConnect,

[andreami]

Hello,
I'm doing some migration tests of win10 pro (from 1802 to 1809) through delivery optimization and wsus.

• Configuration DODownloadMode 1
• Local Firewall open TCP/UDP 7680 ok
• Internet connectivity to https://*.do.dsp.mp.microsoft.com enabel

I can update the workstation by wsus.

The neighboring station does not load my data in peer.

Test-NetConnection xxxx -Port 7680 and ping ok

firewall off for test

The station that is already updated 1809 is in cache
