Original GitHub issue: https://github.com/SpacehuhnTech/esp8266_deauther/issues/1281

This page suggested some websites take the huff if you don't provide some fake browser info, that indeed seemed to be the problem.

I changed the first few lines of update_manf.py to read as below and it cured the problem:

import argparse
from urllib.request import urlopen, Request

WS_MANUF_FILE_URL = "https://code.wireshark.org/review/gitweb?p=wireshark.git;a=blob_plain;f=manuf"
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.3"}
macs = []
vendors = []
tempVendors = []

def padhex(s):
    return '0x' + s[2:].zfill(2)

def parse_options():
    parser = argparse.ArgumentParser()
    parser.add_argument("-o", "--output", help="Output file name for macs list", required=True)
    parser.add_argument("-s", "--small", action='store_true', help="Generate small file only with most used 10 000 macs")
    parser.add_argument("-u", "--url", help="Wireshark oui/manuf file url")

    opt = parser.parse_args()

    return opt

def generate_lists(url, output, small):

    global tempVendors
    global vendors
    global macs

    if url:
        req = Request(url, headers)
        data = urlopen(req)
    else:
        req = Request(url=WS_MANUF_FILE_URL, headers=headers)
        data = urlopen(req)
