Adapter refuses connections after a while

[step21]

Hey.
So after first mistakenly using enh or ens for the ebusd configuration, I got the adapter working.
However, while then setting up everything else, it stopped responding. Neither ebusd or telnet to the data or status port will work, ebusd says

[bus error] device status: transport closed
[bus notice] device invalid

telent says busy on port 3334, and to port 5555 connection works, but the response then is only some numbers like 11371243 after which the connection is closed. they kind of look like a timestamp as they are changing.

Ping does work however. Is there some way to remotely restart the board, without being physically present?

Update: it seems somehow that port 3333 still works. Maybe when connecting to 3334 before, it didn't close the port properly? However I couldn't find any service that still acesses it.
