When I attempt to connect to dgraph, I follow the example write like this:

```auto
from pydgraph.client import DgraphClient

dg_client = DgraphClient('localhost',8080)

response = dg_client.query("""
         mutation
        {
             set
             {
                 <alice> <name> \"Alice\" .
                 <greg> <name> \"Greg\" .
                 <alice> <follows> <greg> .
             }
         }""")

```

there comes an error like this:  
`I1026 16:20:47.341823000 140735514100544 subchannel.c:642] Connect failed: {"created":"@1509006047.341751000","description":"Failed to connect to remote host","errno":35,"file":"src/core/lib/iomgr/error.c","file_line":246,"os_error":"Connection refused","target_address":"ipv6:[::1]:8080"} I1026 16:20:47.341858000 140735514100544 subchannel.c:647] Retry in 0.898440040 seconds E1026 16:20:47.342815000 140735514100544 chttp2_transport.c:1810] close_transport: {"created":"@1509006047.342749000","description":"Failed parsing HTTP/2","file":"src/core/ext/transport/chttp2/transport/chttp2_transport.c","file_line":1726,"referenced_errors":[{"created":"@1509006047.342727000","description":"Expected SETTINGS frame as the first frame, got frame type 80","file":"src/core/ext/transport/chttp2/transport/parsing.c","file_line":477}]} Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/anaconda2/lib/python2.7/site-packages/pydgraph/client.py", line 38, in query response = self.stub.Query(request, timeout) File "/anaconda2/lib/python2.7/site-packages/grpc/beta/_client_adaptations.py", line 300, in __call__ self._request_serializer, self._response_deserializer) File "/anaconda2/lib/python2.7/site-packages/grpc/beta/_client_adaptations.py", line 198, in _blocking_unary_unary raise _abortion_error(rpc_error_call) grpc.framework.interfaces.face.face.AbortionError: AbortionError(code=StatusCode.UNAVAILABLE, details="")`

In browser, my dgraph can run correctly, but it goes something wrong when I want to use python connect it.

Can anybody help me?

This client hasn’t been maintained for a while. So, no ideas what state it is in at the moment. We have plans to maintain the Python client, though no ETA yet. Community contributions are welcome!

The client has been updated for Dgraph v1.0.0 and the connection should now work properly.
