Failed to open http://localhost:3001

[KristenZHANG]

Hi,

I encountered a problem about managing the Virtuoso service and want to seek some help. Thanks in advance!
I followed the instruction:

1. downloaded both virtuoso_db.zip via wget and virtuoso-opensource.x86_64-generic_glibc25-linux-gnu.tar.gz and unzip all.
2. change the virtuosoPath in virtuoso.py to local virtuoso-opensource path
3. put virtuoso_db under the same directory as the script virtuoso.py
4. ran python3 virtuoso.py start 3001 -d virtuoso_db

However, I cannot open it via http://localhost:3001.

Here is the shell output

Does anyone know the possible reason for that? Thanks!

Did you manage to solve the problem? I'm facing the same issue

[liujiangning30]

http://localhost:3001/sparql is ok.
