Windows server won't setup IP address even though it was correctly assigned.
In this case you need to set IPv6 statically. You can find both assigned addresses IPv4 and IPv6 in detail of your cloudserver dashboard in order to set them in adapter Properties. Only IPv6 is needed to be configured as static.
Gateway is 2a00:1ed0:17::1 and mask is 64
