Hi there,

I created a python UI with the dash but recently sometimes run into the following error message:

```auto
80.82.65.74 - - [08/Jun/2020 00:18:52] code 400, message Bad request syntax ('\x05\x01\x00')
----------------------------------------
Exception happened during processing of request from ('80.82.65.74', 36310)
Traceback (most recent call last):
  File "/usr/lib/python2.7/SocketServer.py", line 596, in process_request_thread

    elif self.parse_request():
  File "/usr/lib/python2.7/BaseHTTPServer.py", line 286, in parse_request
    self.send_error(400, "Bad request syntax (%r)" % requestline)
  File "/usr/lib/python2.7/BaseHTTPServer.py", line 384, in send_error
    self.wfile.write(content)
IOError: [Errno 32] Broken pipe

```

Moreover, the bad request always comes from the same above IP.

I am using dash 1.8.0.

Thanks for any insight into this issue.
