We are using this framework ( https://github.com/amosavian/FileProvider) and we were adding a new feature to support ftp storage. When we are building the app on an a device with iOS 9 everything works fine and I can list all the files from the ftp server BUT when I try to build the app on an a device with iOS 11 I'm always getting a "The operation timed out"
What is happening is that I first open a connection and get response with code 331 and I'm setting a password after that. The second response I get is with code 230 and after that I get a response with code 227 ( entering passive mode) and after the timeout limit the app returns a error saying "The operation timed out"
I searcher everywhere but I cannot find a logical explanation for this.
