General Upload Error: 3800 can occur when an upload does not complete. This can happen due to an unexpected server or network condition.

When you observe this error, it will be accompanied by a more revealing message context that can help you understand the actual problem, such as:

$ Logging /users/miadmin/example.txt to Destination/Filepath size 0 err 3800 Interrupted. Did NOT complete task against '/users/miadmin/example.txt' on 'SSH Host Example'

Common Causes

Common causes of Error 3800 can include:
  • Insufficient disk space on the MOVEit server.
  • File size limits or quota restrictions were exceeded.
  • Permission problems on the destination folder.
  • Antivirus or DLP/content-scanning software blocked the upload.
  • Network interruptions during transfer.
  • FTP/SFTP/HTTPS configuration issues.
  • Temporary server-side application errors.

Troubleshooting Tips

The following tips can help if you observe and are trying to root cause a 3800 code.

  • For added context, you can refer to reports or user logs generated during this time period. For example, MOVEit Audit logs can indicate user or administrator activity that could impact upload policies. HTTP or SFTP logs can indicate server errors, size, and duration of connection.
  • Check the size of the file transfer that failed. Try to transfer a smaller file from the same client location using the same user account.
  • Check available disk space on the MOVEit server.
  • Verify the user's quota and folder permissions.
  • Confirm the file is not being blocked by antivirus or DLP scanning policies.
  • Check IIS, FTP/SFTP, or proxy logs (depending on the protocol being used).
  • If the error occurs through an API, inspect the full API response body because it often contains a more specific explanation than the numeric code.

Has there been Recent MOVEit or Network Maintenance or Upgrades?

If you have had recent upgrades to MOVEit servers, and you have an image of an older system you can test, you can validate that the upload error is not due to new system software or settings.

In the uncommon case that network connection or session aging rules were recently tightened at the firewall, and you have large file transfers making good progress before they time out, you can ask your site engineers for better session aging or keepalive interval values.
