Users of Acronis Cyber Files app, managed with MobileIron, and with AppTunnel set up, cannot copy/move files bigger than 2 GB from one server to another, or from a data source on a server to their Sync & Share space.
When trying to accomplish this operation, the copying process doesn’t start and the following message is displayed:
Copy operation failed. Failed to load URL (Error code: 503).
This is caused by a limitation of the MobileIron Sentry server – a standalone Sentry server does not handle HTTP response with Content-Length larger than 2 GB.
MobileIron doesn’t intent to change this behavior for the moment, so the possible solutions are:
- To split the files bigger than 2 GB into smaller ones before transferring.
- To move the files bigger than 2 GB to a host that does not require AppTunnel.
