error log

Sep 05 21:06:57.000 [warn] We were supposed to connect to bridge '19*.***.***.***:1****' using pluggable transport 'obfs3', but we can't find a pluggable transport proxy supporting 'obfs3'. This can happen if you haven't provided a ClientTransportPlugin line, or if your pluggable transport proxy stopped running.

Try with:

ClientTransportPlugin obfs3 exec /usr/bin/obfsproxy --managed

bridge 19*...:1*

When compiling OBFS proxy, you'll see a set of options, enabling or disabling some features, including obfs3, so try to compile it by hand from the latest git tree
