Azure filesync Server Registration Issue
Azure FileSync Server
registration - Unable to discover
Registering a server with Azure File Sync establishes a trust relationship between Windows Server and Azure. This relationship can then be used to create server endpoints on the server, which represent specific folders that should be synced with an Azure file share
Register a server with Storage Sync Service
Before a server can be used as a server endpoint in an Azure File Sync sync group, it must be registered with a Storage Sync Service.
As part of Azure file sync registration setup, when we run Azure FileSync server
registration in Non internet facing workloads, you may struck at the following window (Azure Resources Manager (ARM) discover URL)
These discover URLS are region specific , more details find the link below
https://learn.microsoft.com/en-US/azure/storage/file-sync/file-sync-firewall-and-proxy
However, if you provided region specific URL's on Non-Internet facing servers, it prompt below error
Observations:-
Azure File Sync server registration services are unable to communicate to backed Azure URLs, due to this server being unable to reach Azure Resource Manager Discovery URLs
If the VM is not allowed to access internet, we need to
ensure that all the required URL and ports are open in Firewall
URL’s need to be whitelisted in the Firewall
*.afs.azure.net : 443
*.one.microsoft.com : 443
*.core.windows.net : 443
*.go.microsoft.com : 443
*.aadcdn.msftauth.net : 334
