Issue/Introduction
HCX Bulk Migration fails during the initial synchronization phase.
The migration workflow terminates with a generic "Initial sync failed Error running request" message in the user interface.
Environment
VMware HCX
Cause
The Hybrid Cloud Services (HCX) Manager is encountering a 403 Access Denied error when attempting to communicate with remote services via Proxy.
Resolution
It is imperative to disable or whitelist the sites in the proxy configuration on both the HCX Connector and HCX Cloud systems to ensure unhindered communication.
Failed migration tasks must be cancelled to clear the current stuck state in the database.
A new mobility group should be created to initiate a fresh migration attempt after the proxy settings are removed.
Refer to the internal documentation regarding environment prerequisites to ensure all required ports are open without proxy interception.
- Refer to the Configure a Proxy Server
Additional Information
Documentation regarding similar behavior can be found in KB 321566.
Ensure that the management network can reach the required endpoints directly as per the documented port requirements.
