# Why Are Event Data Uploads From S3 Failing Due to a Timeout Error?

> Resolve 504 timeout errors when uploading event data from S3 to MoEngage. Reduce files per folder and reorganize your bucket structure to fix imports.

## Problem

A timeout error (504 error response) occurs when attempting to set up a new Simple Storage Service (S3) import.

## Cause

The error occurs because the specified folder contains too many files, which exceeds your system's processing capacity.

## Solution

Perform the following steps:

1. **Check the number of files**:
   * Verify the total number of files in the folder causing the issue.
2. **Organize files into separate folders**:
   * Segregate files into different folders based on their purpose, such as event or user imports.
3. **Create a new folder**:
   * Add only the necessary files to the new folder as a workaround.
4. **Remove files after import**:
   * After the files have been imported successfully, remove them from the folder to prevent future issues.

<Info>
  The maximum timeout limit is 5 minutes.
