Failure in Socket Connection (with proxy)

Hi,
When I run _python run.py config.json -I "/full/path/input/file" -O "/full/path/output/" -E "features"_, I get the following errors:
- **failed CONNECT via proxy status: 403**
- **Exception: Image Input Path not in proper format. [to a jpeg image path]**
- **AttributeError: 'NoneType' object has no attribute 'disconnect'**
