sunpowerconsole.com timing out about sunpower-pvs-exporter HOT 3 OPEN

I too am running into this issue.
I thought it might be because of the multihome raspberry pi that I am running it on, and the dns lookup was going the default route (I don't think sunpowerconsole.com is resolvable over the internet), so I used the parameter --hostname and passed in 172.27.153.1, and I still get the same issue.
Like @kskenyon the commands all work fine using curl.

I found there is a way to force the python app to connect to the right interface, following information I found here:
https://stackoverflow.com/questions/28773033/python-requests-how-to-bind-to-different-source-ip-for-each-request
In exporter.py I added two lines as shown below. Note, however, the IP address needs to match the IP address that it received from the PVS unit. It could change, so, this patch is a hack to get it working.

    def __init__(self,
                 # hostname="sunpowerconsole.com",
                 hostname="172.27.153.1",
                 port=80,
                 scheme="http",
                 timeout=(5, 5),
                 use_device_data_timestamp=False,
                ):
        self.session = requests.Session()

        # The following two lines force the URL binding to happen on the PVS interface
        new_source = source.SourceAddressAdapter("172.27.153.156")
        self.session.mount('http://', new_source)

        self.use_device_data_timestamp = use_device_data_timestamp

        self.timeout = timeout
        self.url = "{scheme}://{hostname}:{port}/cgi-bin/dl_cgi".format(
            scheme=scheme,
            hostname=hostname,
            port=port
        )

If you make the change I suggested above, make sure that you first install the python library
pip install requests_toolbelt
and also add at the top of the exporter.py file:
from requests_toolbelt.adapters import source
otherwise it will fail to run because 'source' is not defined.
