Connection Error: 'channel 3: open failed: connect failed: Connection refused'

Open sangjun927 opened this issue 4 years ago • 2 comments

Hello, I've been using Blazegraph for several months without any issues. However, two days ago, I received an error command via terminal. An issue has been described below.

Error description: Connecting localhost:9999 is working fine. However, when I try to execute the query via Blazegraph, the error message comes out from terminal and query output.

  1. Command line from terminal after executing query: channel 3: open failed: connect failed: Connection refused

  2. Output from Blazegraph after executing query: ERROR:Could not contact server

Your comment would be highly appreciated. Thanks.

Can you post the log for where the Blazegraph server is running?

Hello, here are some updates. Fortunately, we solved the problem. The server had rebooted and there was a problem with the java version. Now, we fix the issue, and it runs well. Thank you for the comments!
