You may see an error similar to the following in your license status:

VPS licenses have a 2GB RAM limit and Ultra VPS licenses have an 8GB RAM limit. You cannot use such license on servers that would go over these limits. 1-CPU licenses and up do not have such hardware limitations.

For example, in the above error, a VPS license cannot be used on a VPS with 16GBs of RAM. You will need to upgrade the license to a 1-CPU license or greater for this particular server.
