Hi @Anping Li
Please verify if you can create a server in a different region. This error is likely due to a temporary capacity constraint in 'West US 2' region.
If your business specifically requires creating a server in the 'West US2' region, it's possible that your subscription needs capacity for server creation.
To address this, you may need to open a support case under the problem type 'Capacity, Limits, and Quotas.'
Hopefully, the platform team will allocate the necessary capacity to your subscription, enabling server creation in that region. If not, they should be able to provide the required information.
Thank you!
