Intermittent issues with SMB over QUIC (Server 2022 Datacenter Azure Edition)
Hi, we're trying to implement SMB over QUIC using a Windows 2022 server syncing with an Azure File Share. This seems to work fine in the first place - when we bring up the server and map the drive on...
Does anyone have an idea? Already verified few more things:
- Certificate (used for both, QUIC and KDC proxy) is from corporate CA and trusted by the clients
- Ports are open (clients can reach tcp/443 and udp/443)
- SMB signing is not required on client side
- Group Policy for KDC proxy includes all UPN suffixes
Still, connections stop with "The specified network name is no longer available" after a while or after reboot. Then unmapping/mapping, or restarting workstation service bring it back. Reboot usually does NOT with the drive persistently mapped. Rebooting without the drive mapped, and then mapping it after reboot does usually work.
