Rclone Time's out in like 1 minute

i hit rclone's endpoint :

https://dev.apps.api.it.philips.com/rclone/sync/move

below is my request body from postman :

{
    "srcFs": "SimToolsFTPServer1:/Export/Temp_RCDH/",
    "srcRemote": "/Export/Temp_RCDH/",
    "dstFs": "test:/data/CHBULKUPLOAD/LOCALTESTING/Dst3/",
    "dstRemote": "/data/CHBULKUPLOAD/LOCALTESTING/Dst3/",
    "_async": false,
    "_filter": {
        "IncludeRule": [
            "File_2GB_of_size.csv"       
        ]
    }   
}

below is the response i recieved :

<html>
<head><title>504 Gateway Time-out</title></head>
<body>
<center><h1>504 Gateway Time-out</h1></center>
<hr><center>nginx</center>
</body>
</html>

I wanted to move 2gb file but it is taking a lot of time to move it, and in response rclone gives me timeout why? how to resolve this, it is taking more time to move more than 1 gb files.

You should run long lasting jobs in async mode:

otherwise HTTP request indeed times out after 1 min.

oh yes you are absolutely correct.
Thank you
