client requested valid, but unconfigured authentication method

[oberstet]

When a client requests a valid but unconfigured authmethod on rawsocket, the respective log message ("client requested valid, but unconfigured authentication method cryptosign") is only printed at log level "debug", and the client is never notified of the failed auth (but hangs):

Is there any way around this problem?

you could change log level to "info" here https://github.com/crossbario/crossbar/blob/71787f9eae220966e6be4a608cc049e336f9a85b/crossbar/router/session.py#L924
