Welcome to Skyline Communities!!!

The possible reasons for log failures while uploading huge files can be any of the following reasons:

• A minimum of 3Mb/s external network bandwidth for the sending of large files (support bundles) could not have been met

• Proxy might not be configured to allow large files, in case of the proxy being used.

• If the log transfer request did not complete in the maximum allowed time of 6 hours
