Error when deploying OVA in VMware vsphere ESXi 6.5.

When I try to deploy OVA in the following environment, I get the following error message and eventually the deployment does not complete.When I searched on the web, it was stated that I should change to a standard SW port group instead of a distributed SW port group.

However, the reason is not written, and changing from a distributed SW port group to a standard SW port group requires a significant change in the environment, so please tell me the reason.Or tell me other workarounds.
