Did you guys ever get this resolved? I upgraded my ProxMox5.4 to 6 and the upgrade seemed fine, but ive notcied my Windows 2012R2 servers using e1000 nic's are now failing - they were working fine before the upgrade.
Maybe a compatibility trouble with drivers
Did you update the Windows drivers ?
You could change to Virtio (best practice) ... with the ISO Windows drivers
