For lab purposes, when configuring a VCF 9.0 or 9.1 Offline Depot, you can streamline the infrastructure setup by configuring the VCF Installer to use HTTP instead of HTTPS, which is the default configuration from the VCF Installer.
Alternatively, if you decide to use the system default which will expect the VCF Offline Depot to be served over HTTPS, you might be using a self-signed TLS certificate. If you attempt to connect to your offline depot with the VCF Installer, you probably will hit the following error as the TLS certificate is not trusted by the VCF Installer, which is expected.

In VCF 5.x, the workaround was to import your TLS certificate chain into SDDC Manager's certificate store which would then allow the trust to be established.
The exact same solution is required for the VCF Installer, but the path to the certificate store has changed.
