Large File FTP Upload Error '[WinError 10054] An existing connection was forcibly closed by the remote host' - Small Files Succesful

Question

I have been having trouble with a File upload via FTP. I can upload small files and get a 226 stored message that everything works. When I run a larger file (200mbs) that takes about 15 minutes to upload, I see that the file uploads when I look at FileZilla but I get the following error that breaks my try/except in python:

[WinError 10054] An existing connection was forcibly closed by the remote host

Here is my script (Thanks to this answered question, I was able to actually get my files uploaded using SmartFTP - Cannot list FTP directory using ftplib – but FTP client works):

class SmartFTP(FTP):
    def makepasv(self):
        invalidhost, port = super(SmartFTP, self).makepasv()
        return self.host, port


try:
    for file_name in os.listdir(fullPath):
        if file_name == 'file.csv':
            
            file_path = fullPath + "\\" + file_name
            print('Moving File - ' + file_path + ': ' + str(datetime.now()))
            
            with SmartFTP(FTP_HOST, FTP_USER, FTP_PASS, timeout=2700) as ftp, open(file_path, 'rb') as file:
                ftp.set_debuglevel(2)
                print('here1')
                test = ftp.pwd()
                print('here2')
                ftp.storbinary(f'STOR {file_name}', file)
                print('here3')
                print('FTP Move Completed')
                

except Exception as e:
    print("FTP and File Move process failed: " + str(e))

Moving File - file.csv: 2022-07-12 15:27:35.932522

here1

*cmd* 'PWD'

*put* 'PWD\r\n'

*get* '257 "/folder"\n'
*resp* '257 "/folder"'
here2
*cmd* 'TYPE I'
*put* 'TYPE I\r\n'
*get* '200 Transfer Mode: BINARY\n'
*resp* '200 Transfer Mode: BINARY'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering PASV Mode (numbers)\n'
*resp* '227 Entering PASV Mode (numbers)'
*cmd* 'STOR file.csv'
*put* 'STOR file.csv\r\n'
*get* '150 Connecting Data Port...\n'
*resp* '150 Connecting Data Port...'

Then it loads for about 15 minutes

*cmd* 'QUIT'
*put* 'QUIT\r\n'
FTP and File Move process failed: [WinError 10054] An existing connection was forcibly closed by the remote host

This what happens when I load a smaller file:

Moving File - file.csv: 2022-07-12 15:50:39.489980

*cmd* 'PWD'
*put* 'PWD\r\n'
*get* '257 "/Atlas_In"\n'
*resp* '257 "/Atlas_In"'
here2

*put* 'TYPE I\r\n'
*get* '200 Transfer Mode: BINARY\n'
*resp* '200 Transfer Mode: BINARY'
*cmd* 'PASV'
*put* 'PASV\r\n'
*get* '227 Entering PASV Mode (numbers)\n'
*resp* '227 Entering PASV Mode (numbers)'
*cmd* 'STOR file.csv'
*put* 'STOR file.csv\r\n'
*get* '150 Connecting Data Port...\n'
*resp* '150 Connecting Data Port...'
*get* '226 Stored Message: [file.csv] Byte Count: [57824] bytes\n'
*resp* '226 Stored Message: [file.csv] Byte Count: [57824] bytes'
here3
FTP Move Completed
*cmd* 'QUIT'
*put* 'QUIT\r\n'
*get* '221 GoodBye\n'
*resp* '221 GoodBye'

They have a process that moves files from the folder I'm posting, into a downloaded folder. Is this what is causing the issue?

I have tried setting the ftp.set_pasv(False), but this equates in the process loading forever (no end).

As requested, here is the log (and error) of what happens when loaded via FileZilla:

Fails here then retries (filezilla settings are to try twice I believe)

Is there anything else I can try? Thanks so much for any help!
