This error indicates that a file download operation failed. Error code 3600 is a general failure code and typically indicates that the file transfer was interrupted by a condition outside of MOVEit Automation.

The error is often accompanied by additional information in the task log that identifies the underlying problem. For example: 
$ Logging \\Share\FILE.PDF to size 0 err 3600
The semaphore timeout period has expired.

Common causes

Common causes of Error 3600 include:
  1. Network connectivity interruptions.
  2. Storage or device communication issues.
  3. File corruption.
  4. Antivirus or other software interfering with access to the file.
  5. Problems accessing files on network shares or remote storage.

Network-related failures

If the error occurs repeatedly, review the task log for additional details and work with your network or system administrators to identify any issues affecting connectivity between MOVEit Automation and the source system. Network tracing or packet capture tools can help identify where communication is failing

UNC share errors

The following messages may indicate a problem with a file stored on a network share: 
Task "x": Failed to retrieve local file \\Share\FILE.PDF on try 1 of 1:
A device attached to the system is not functioning.

$ Logging \\Share\FILE.PDF to size 0 err 3600
