/etc/sysconfig/proxy on individual hosts does not resolve the connectivity issue.VMware Cloud Foundation 9.1
In VCF 9.1, management services components such as fleet and the Software Depot service are separated into independent services. Configuring the proxy within the VCF Operations global settings (Administration > Global Settings > Network Settings) only applies the configuration to the VCF Operations application itself. It does not automatically propagate to the underlying VCF management services components or the proxy-forwarder used by these services.
To resolve this issue, you must separately configure the proxy settings for the VCF management services components.
Detailed procedural steps and specific UI paths can be found in the technical documentation:
