Hi You are most likely facing one of 2 issues (if you are using FTPS/FTPES): - One of the firewalls in between you client and the server are blocking the data port range. - In high load situations the server might not have enough data ports defined to match the requests or it might be venturing into a data port range that once again is not open on the firewalls.
