Since the server maintenance, upgrade. Impossible to upload using your FTP. (ftp.storagemadeeasy.com)They can log on the ftp server but no file transfer.
I am realizing from some logs that in passive mode the server is sending an address that cannot be resolved.
Log extract: “Server sent passive reply with unroutable address”
I have tried multiple FTP client to test but only one worked, because it was smart enough to reroute to the original server address, but all other failed.
