ERROR_VMCOMPUTE_CONNECT_FAILED

Hyper-V-isolated containers depend on a host-to-guest control channel

ERROR_VMCOMPUTE_CONNECT_FAILED concerns communication with the virtual machine that hosts a container, rather than ordinary network connectivity from the container to an application endpoint. In Hyper-V isolation, host-side HCS coordinates with guest-side compute services inside a utility VM.

A failure can arise when the utility VM did not boot correctly, the guest compute service is unavailable, the negotiated transport cannot be established, or security and version assumptions differ between host and guest components.

Evidence and corrective action

Confirm whether the workload uses Hyper-V isolation; process-isolated containers do not use the same guest control path.
Collect utility-VM startup and Host Compute Service events before testing application network ports.
Verify that the base image and host servicing levels form a supported combination.
Check whether endpoint security or virtualization policy interferes with the host/guest transport.
Recreate the utility VM only after preserving the first connection failure and its HCS result document.
