I have seen these behaviour in several different steps during the test execution.
Can someone help me whats the problem is or how we can solve it?

Connect to web server using python3 socket

I'm running Python3 running Django on localhost and listening to http://127.0.0.1:8000/
and I want to test it by different ways like request and socket
import requests
res = requests.request("GET", "http://127.0.0.1:8000/")
txt = res.content
print(res)
res.close()
# <Response [200]>
It runs well, and
on my running Django console, it shows [07/Jul/2018 16:04:26] "GET / HTTP/1.1" 200 6744
Now instead requests to socket
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(('127.0.0.1', 8000))
msg = b'GET / HTTP/1.1'
s.send(msg)
print(s)
s.close()
# <socket.socket fd=1324, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('127.0.0.1', 55312), raddr=('127.0.0.1', 8000)>
No error shows in my program
But I got the following exception on my running Django console

I'm new to socket programming and just start learning networking, I think maybe I should send more request head. Please tell me how to do that, thanks.
Yes, you need to send more data. A minimal HTTP 1.1 request requires a second line that contains a Host header specifying the name or address of the host that should handle the request, and the request header lines must be followed by an empty line to tell the server that the header has been completely received.
In HTTP the end of a line is indicated by a pair of characters, a carriage return and a line feed. In Python strings \r represents a carriage return and \n represents a line feed. (The line feed character is sometimes called a newline character, hence the \n code.) This means that you have to write \r\n to mark the end of each line in the request.
So, what you need is:
msg = b'GET / HTTP/1.1\r\nHost: 127.0.0.1\r\n\r\n'
The final \r\n produces the empty line that indicates the end of the headers.
After you make that change it's likely that your server will report a different error, because your client program closes its socket immediately. That breaks the connection between the client and the server. When the server tries to send its response, it will find that the connection has been broken and it will probably complain about that. To avoid that, change your client to use s.recv to wait for and read the response from the server after it does s.send(). Something like:
while True:
resp = s.recv(8000)
if resp:
print resp
else:
break

Any help please?
I got two solution for this from here, one is to remove the pid file /var/run/nginx-nr-agent/nginx-nr-agent.pid and than start/restart it. And second solution is to restart the server.
