At login sequence I got an error message: “Address already in use”.
What it means ?
There are a listing of error messages ? I do not found.
That’s an odd timing to get that sort of an error…
What API client are you using? What is the code that results in this error? Are you connecting directly to the router, or over a VPN or SSH tunnel?
I can imagine several scenarios where this can happen, but none of them involve connecting directly to a router with any normal API client and immediatly catching errors specifically from that API client.
