FTP Put file via MyRio1900 Error 59 (TCP Open Connection)

Hello everybody and thank you in advance for your help. I'm trying to upload a file from a MyRio 1900 on a FTP Server. On my pc the code works, but when i ran it on the MyRio it gave me Error 59 (TCP Open connection. Possible reason: the network is down, unreachable or has been reset). I'm trying to upload it connecting the MyRio to a modem via WiFi. Attached the project.

Thank you in advance to everyone who helps me with this problem.
