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 tim
