When I start the program to share files to client it received it but when i request for another file download it failed with this error.
Now i keep getting this error from the client
socket1.send(bytes('0', 'UTF-8'))
BrokenPipeError: [Errno 32] Broken pipe
line 46 client.py
I tried breaking out of the server's filedownload loop but still not working. server

Please can anyone help me,i don't know to fix it. I'll appreciate any help. Thanks
