Android Question Getting java.net.SocketException: Connection reset error

I have an app that does a few FTP actions.

I am using okHTTPutils2 v2.82 and B4A 9.01

B4X: 
FTP.List("/images/gallery/")

The above FTP action works fine, so I know the credentials and the connection are ok.

But when I try to create a new directory using a Google Pixel phone running SDK 28, it gives a "java.net.SocketException: Connection reset" error:

B4X: 
FTP.SendCommand("MKD","/images/Gallery/" & NewDirName)

It works in the emulator running SDK 28, and on a Nexus running SDK 24 and an S4 running SDK 21.

Since the "MKD" (using ".SendCommand") is a "manually-specified" action (and not a built-in action like .Upload or .List) could this have something to do with this error?

How are okhttputils and ftp related here?

The command you suggested allows your app to use HTTP connections instead of HTTPS.

I´m not sure about the error though.
Maybe related to passivemode?

Hi dear Don. I answered this way because he also spoke of okHTTPutils2 ( thing different from FTP ). So having no reference code and thinking that somehow you use okHTTPutils2 i suggested trying that solution

Try add in Manifest:

B4X: 
CreateResourceFromFile(Macro, Core.NetworkClearText)

That fixed it!

Thanks Marco.

Strange how the SDK 28 Emulator image did not "emulate" this problem.
