If you cannot upload, verify that your network is using a proxy. You can set the proxy by using the following command line options:


```
Linux:
  embulk -J-Dhttp.proxyHost=xxxx -J-Dhttp.proxyPort=xxxx -J-Dhttp.proxyUser=xxxx -J-Dhttp.proxyPassword=xxxx run config.yml
Windows:
  embulk.bat "-J-Dhttps.proxyHost=xxxx" "-J-Dhttps.proxyPort=xxxx" "-J-Dhttp.proxyUser=xxxx" "-J-Dhttp.proxyPassword=xxxx" run config.yml
Or,
  "java"  -Dhttps.proxyHost="host" -Dhttps.proxyPort="port" -jar embulk.bat run config.yml
```
