Lnd: CMGR: Can't accept connection: chacha20poly1305: message authentication failed

[whizz]

I don't know if this is actually a problem, but every now and then the log contains this message.

2017-12-18 10:39:58.600 [ERR] CMGR: Can't accept connection: chacha20poly1305: message authentication failed

As there is no other detail in the log, I cannot determine what authentication failed and why. Maybe at least the error message should be clearer as what to do about it.

I am able to connect to peers.

There's no issue there. That's just the way that brontide works: if the connecting party doesn't know your pubkey, then you won't connect to them.

On the network as is, this can happen if you've wiped your state in the past and have a new public key, yet older nodes are still trying to connect using your prior public key.

And this error will still forever for older nodes? Then this will be an issue...

Error for ever? If I open up a socket to your node, and try to send let's say TLS traffic, you'll get this issue. This can also arise if someone is port scanning you in an attempt to see what network facing services you're running.
