SCP not connecting with an RSA key

[slytherin]

Whenever I try to connect to my server using SCP with an RSA key, it throws an error: Session.connect: java.io.IOException: End of IO Stream Read

This is when connecting to a FreeBSD 11.1-RELEASE server, using the most current version of AndFTP and Android Oreo. This appears to be a client error from what I've found from googling (including a similar error mentioned here on the this forum a year ago).

I'm not sure what more information I can provide that you can use, but I'll help however I can if it means this will be fixed.

Could you try AndFTP 5.0 and enable Legacy SSH as explained here:
