Re: [Bigdata-developers] Blazegraph Docker problem: "ERROR: Could not contact server"

[Mikel E. A. <mik...@gm...>]

Hi;

I'm still getting the same error. I can access
http://127.0.0.1:9999/bigdata/#splash but then if I access the container's
IP (obtained with inspect, 172.17.0.4) the connection is refused:

mikel@durruti:~$wget
http://172.17.0.4:9999/bigdata/sparql?query=select%20*%20where%20{%20?s%20?p%20?o%20}%20limit%201
Konektatzen 172.17.0.4:9999... huts egin da: Connection refused

Thanks
