[tor-relays] How to troubleshoot obfs4 bridge?

[Tim Sammut]

Hi.

I've configured my bridge to support obfs3 and obfs4 transports using
the debian obfs4proxy package from
http://deb.torproject.org/torproject.org. Connecting to the bridge using
TBB 4.5a4 works for obfs3 but not obfs4.

TBB produces this error:

    [warn] Proxy Client: unable to connect to x.x.x.x:41980 ("server
    rejected connection")

The bridge line I am supplying to TBB looks like:

    bridge obfs4 x.x.x.x:41980

On the bridge side, it looks like the bridge is listening for obfs3 and
obfs4 via the following log entries:

    Tor[21544]: Registered server transport 'obfs3' at '[::]:51161'
    Tor[21544]: Registered server transport 'obfs4' at '[::]:41980'

The relevant parts of my bridge config are:

    ORPort 443
    ExtORPort auto
    BridgeRelay 1
    ServerTransportPlugin obfs3,obfs4 exec /usr/bin/obfs4proxy

Should this be working? How can I troubleshoot this?

Thanks!

hope you are well
