SSL Error calling /arcgis/admin/uploads/upload

Hello, I am trying to change update a SOE via Python script. I am using /arcgis/admin/uploads/upload POST request, but I am getting an error.

# minimal example of changing an SOE

import arcpy, os, httplib, json, socket, sys, urllib, requests

username = 'admin'
password = 'enter_password_here'

# get IPV4 address
hostname = socket.gethostname()
serverName = socket.gethostbyname(hostname) # IPV4 Address

serverPort = 6080

def getToken(username, password, serverName, serverPort):
    tokenURL = "/arcgis/admin/generateToken"
    params = urllib.urlencode({'username': username, 'password': password, 'client': 'requestip', 'f': 'json'})
    headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}

    # Connect to URL and post parameters
    httpConn = httplib.HTTPConnection(serverName, serverPort)
    httpConn.request("POST", tokenURL, params, headers)

    # Read response
    response = httpConn.getresponse()
    if (response.status != 200):
        httpConn.close()
        print("Error while fetching tokens from admin URL. Please check the URL and try again.")
        return
    else:
        data = response.read()
        httpConn.close()

        obj = json.loads(data)
        if 'status' in obj and obj['status'] == "error":
            return

        # Extract the token from it
        return obj['token']

token = getToken(username, password, serverName, serverPort)

soe_path = r"C:\Users\test-user\Documents\SOI_Test1.soe"

# upload the soe file
upload_url = "https://localhost:6443/arcgis/admin/uploads/upload?f=json"

print(token)
import requests
with open(soe_path, 'rb') as f:
    data = {
        "token": token
    }
    response = requests.post(upload_url, data, files={'itemFile': f})

    print(response)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I am just getting a token and using it to try to call /arcgis/admin/uploads/upload. The post request gives error:

  File "C:\Users\test-user\Documents\change_soe.py", line 53, in <module>
    response = requests.post(upload_url, data, files={'itemFile': f})
  File "C:\Python27\ArcGIS10.7\lib\site-packages\requests\api.py", line 110, in post
    return request('post', url, data=data, json=json, **kwargs)
  File "C:\Python27\ArcGIS10.7\lib\site-packages\requests\api.py", line 56, in request
    return session.request(method=method, url=url, **kwargs)
  File "C:\Python27\ArcGIS10.7\lib\site-packages\requests\sessions.py", line 475, in request
    resp = self.send(prep, **send_kwargs)
  File "C:\Python27\ArcGIS10.7\lib\site-packages\requests\sessions.py", line 596, in send
    r = adapter.send(request, **kwargs)
  File "C:\Python27\ArcGIS10.7\lib\site-packages\requests\adapters.py", line 497, in send
    raise SSLError(e, request=request)
requests.exceptions.SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:727)‍‍‍‍‍‍‍‍‍‍‍‍‍

The token works with /arcgis/admin/services/FOLDER/SERVICE_NAME.MapServer/edit, but I used httplib.HTTPConnection request method. I am not sure why it is not working with requests library here.

Same POST request that succeeds with httplib.HTTPConnection will fail with requests.post (example below). I am using AWS EC2, but I think it may be due to the REST API used, since I can use request.posts sucessfully with other https URLs.

import arcpy, os, httplib, json, socket, sys, urllib, requests

username = 'admin'
password = 'enter_pass_here'

# get IPV4 address
hostname = socket.gethostname()
serverName = socket.gethostbyname(hostname) # IPV4 Address

serverPort = 6080

def getToken(username, password, serverName, serverPort):
    tokenURL = "/arcgis/admin/generateToken"
    params = urllib.urlencode({'username': username, 'password': password, 'client': 'requestip', 'f': 'json'})
    headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}

    # Connect to URL and post parameters
    httpConn = httplib.HTTPConnection(serverName, serverPort)
    httpConn.request("POST", tokenURL, params, headers)

    # Read response
    response = httpConn.getresponse()
    if (response.status != 200):
        httpConn.close()
        print("Error while fetching tokens from admin URL. Please check the URL and try again.")
        return
    else:
        data = response.read()
        httpConn.close()

        obj = json.loads(data)
        if 'status' in obj and obj['status'] == "error":
            return

        # Extract the token from it
        return obj['token']

token = getToken(username, password, serverName, serverPort)

serviceUrl = "https://localhost:6443/arcgis/admin/services/FOLDER/SERVICE_NAME.MapServer"

headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/plain"}

params = urllib.urlencode({
    'f': 'json',
    'token': token
})

# SSL error
# response = requests.post(serviceUrl, params, headers=headers)
# print(response.text)

# this works
httpConn = httplib.HTTPConnection(serverName, serverPort)
httpConn.request("POST", serviceUrl, params, headers)
response = httpConn.getresponse()
print(response.read())‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

use verify = False if you don't need verify ssl certificate

requests.get('https://....', verify=False)
