beta8 bug: "scp" hangs

“ssh” login to the router (hAP ac^2) is ok.
But copying a file from PC to the router using the “scp” command starts the copying, but it then hangs.
On the router a temporary file name is created with size 0 bytes.

(15:00:53) xxx@yyy:~/tmp$ scp -p22 test.rsc admin@192.168.127.254:confused:
admin@192.168.127.254’s password:
test.rsc 100% 2 0.0KB/s 00:00
^C(15:02:01) xxx@yyy:~/tmp$

>

The test.rsc file has size 2 bytes (just a "#\n"). Above I waited more than 60 seconds to finish the transfer and then aborted it with CTRL-C.

On the router it looks like this:

> ```text
[admin@AP1] > /file print 
Columns: NAME, TYPE, SIZE, CREATION-TIME
  #  NAME                            TYPE       SIZE     CREATION-TIME       
  0  0 1593433490 0                  file       0        jun/29/2020 15:01:13
