Problem with Grobid configuration file resources/config.json

[stefanofasciani]

On some machine the following configuration is working

{
"grobid_server": "http://localhost:8070",
"grobid_port": "8070",
"batch_size": 200,
"sleep_time": 5,
"timeout": 60,
"coordinates": [
"persName",
"figure",
"ref",
"biblStruct",
"formula"
]
}

While on other machines the following is working (also "grobid_server": "http://localhost" fails)

{
"grobid_server": "localhost",
"grobid_port": "8070",
"batch_size": 200,
"sleep_time": 5,
"timeout": 60,
"coordinates": [
"persName",
"figure",
"ref",
"biblStruct",
"formula"
]
}
