Remote Office PXE Media issues

Remote Office PXE Media issues

I have 1 remote office that will not publish the PXE media, error:

Unable to publish PXE media files - Network error occurred HTTP error code <404>

There are no communication issues with the server hosting the remote office this is fully reachable from the main Desktop Central server.
The most recent image had no issues replicating to the remote office, I can boot a Virtual machine from the remote office location via the an ISO and this connects to the remote office to pull the image to the machine and images successfully

the only issues seems to be the ability to publish the PXE media.

I have checked and the 'ManageEngine OS Deployer PXE Server' is running.

I would be grateful for any support with this.

Thank you
