Specified Parent Network is Invalid

[BostanHussain2015]

HI,

I am using;

vCD 10.5.1
NSX-V - 6.4.14
NSX-T - 4.0.1.1
vCenter - 7.0.3
Migration Tool - 1.4.2.1

When trying to migrate workloads, i get an error stating 'Specified parent network is invalid. Either it is inaccessible in the vDC or it is not part of the correct organisation. Failed to move vApps.'

I can view the networks error'd via GET https://vcd_UI/api/network/network_UUID, they are v2t networks which exist in the correct vDC.

Will attach a screenshot of the error.

Regards,
Bostan
