I usually use ttyd to enter linux commands on a terminal window inside luci without the need to open an ssh connection to the router.
But sometimes it happens that ttyd does not respond (that is, its windows remains black with the prompt not appearing).
When I connect via ssh and run the command
ttyd start, I get the following message that I'm not able to understand. Can you tell me how to correct the error?
