I tried putting all the Ciphers one-by-one in:


but with no improvement.  I will try ssh debugging . .

I have also sent a note to the developer of SSHDroid to see if (s)he 
responds but the last update to that app was in 2015 and ssh doesn't 
change very much so it is hard to see why that should suddenly be 
playing up - I will also try and use the ssh from Fedora 27/8 to see if 
that makes a difference.
