I try to self host codalab competitions using minion.
I have everything working except that submissions are failed due to the following error:

ssl.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

My hosts is behind a proxy and is certified by letsencrypt.

I can temporary fix it by changing worker.py (inside the competitions-v1-compute-worker container)
and add the line verify=False to the put_blob function. That is,

def put_blob(url, file_path):
    logger.info("Putting blob %s in %s" % (file_path, url))
    requests.put(
        url,
        data=open(file_path, 'rb'),
        headers={
            'x-ms-blob-type': 'BlockBlob',
            'x-ms-version': '2018-03-28',
        },
        verify=False
    )

But this of course is a temporary fix. Can you look into this? Thanks.
