Looks like an auth issue on your end. Don't think there's anything lnd specific here. Double check your config for btcd and lnd to make sure things line up properly.

[AllanLindJensen]

I agree it must be an error my end. When user and pass are identical in btcd.conf and lnd.conf, then

lnd output: "Unable to start server: -32602: parameter #2 'verbosity' must be type int (got bool)"
btcd.log: "[ERR] RPCS: Websocket receive error from 127.0.0.1:50152: websocket: close 1006 unexpected EOF"

[AllanLindJensen]

Should I close this issue, and create a new one?

This looks like the same problem as in #4076.
Make sure you really are using btcd v0.20.1-beta and not master. Any version newer than v0.20.1-beta is not compatible with lnd.
