Why is the connection between a python motor client and a mongoDB being dropped for about 50% of queries?

I'm seeing odd behavior in my application
I have a graphQL python application that lives in a docker container and is using FastAPI and Uvicorn. It connects to a MongoDB in another docker container using Motor. This is run in a Kubernetes instance.
About 50% of the time, but with no real pattern, I won't get results back. The other 50% of the time it works fine.
Based on the mongodb logs it looks like the python application is closing the connection before the response can be sent back. This is not a long running query (< 10ms). Additionally I've tried to set the various timeouts in Motor/PyMongo very high (~3600s) but still get the same behavior.
Client Initialization:
try:
# kwargs contains username, password, connectTimeoutMS, socketTimeoutMS, serverSelectionTimeoutMS
return AsyncIOMotorClient(host, port, appname=appname, connect=True, **kwargs)
except:
#log it
The Query Code:
def callQuery(vendor, name):
match_query = {
"$match": {
"_id.product_vendor": vendor,
"_id.product_name": name,
}
}
add_fields = {
"$addFields": {
"product_name": "$_id.product_name",
"product_vendor": "$_id.product_vendor",
}
}
project = {"$project": {"_id": 0}}
cursor = collection.aggregate([match_query, add_fields, project])
products = await cursor.to_list(length=None) # line 173 in product_lookup to compare to bt below
def submit_aggregation(pipeline: List[dict], collection, **kwargs):
return collection.aggregate(pipeline, **kwargs)

Error trying to connect Celery through SQS using STS

I'm trying to use Celery with SQS as broker. In order to use the SQS from my container I need to assume a role and for that I'm using STS. My code looks like this:
role_info = {
'RoleArn': 'arn:aws:iam::xxxxxxx:role/my-role-execution',
'RoleSessionName': 'roleExecution'
}
sts_client = boto3.client('sts', region_name='eu-central-1')
credentials = sts_client.assume_role(**role_info)
aws_access_key_id = credentials["Credentials"]['AccessKeyId']
aws_secret_access_key = credentials["Credentials"]['SecretAccessKey']
aws_session_token = credentials["Credentials"]["SessionToken"]
os.environ["AWS_ACCESS_KEY_ID"] = aws_access_key_id
os.environ["AWS_SECRET_ACCESS_KEY"] = aws_secret_access_key
os.environ["AWS_DEFAULT_REGION"] = 'eu-central-1'
os.environ["AWS_SESSION_TOKEN"] = aws_session_token
broker = "sqs://"
backend = 'redis://redis-service:6379/0'
celery = Celery('tasks', broker=broker, backend=backend)
celery.conf["task_default_queue"] = 'my-queue'
celery.conf["broker_transport_options"] = {

'predefined_queues': {
'my-queue': {
'url': 'https://sqs.eu-central-1.amazonaws.com/xxxxxxx/my-queue'
}
}
}
In the same file I have the following task:
#celery.task(name='my-queue.my_task')
def my_task(content) -> int:
print("hello")
return 0
When I execute the following code I get an error:

If I use boto3 directly without Celery, I'm able to connect to the queue and retrieve data without this error. I don't know why Celery/Kombu try to list queues when I specify the predefined_queues configuration, tha is used to avoid these behavior (from docs):
If you want Celery to use a set of predefined queues in AWS, and to never attempt to list SQS queues, nor attempt to create or delete them, pass a map of queue names to URLs using the predefined_queue_urls setting
Source here
Anyone know what happens? How I should modify my code in order to make it work?. Seems that Celery is not using the credentials at all.
The versions I'm using:
celery==4.4.7
boto3==1.14.54
kombu==4.5.0
Thanks!
PS: I created and issue in Github to track if this can be a library error or not...

I solved the problem updating dependencies to the latest versions:
celery==5.0.0
boto3==1.14.54
kombu==5.0.2
pycurl==7.43.0.6

I was able to get celery==4.4.7 and kombu==4.6.11 working by setting the following configuration option:
celery.conf["task_create_missing_queues"] = False

Django Closed Socket Error with Repeated AJAX Calls [WinError 10053] An established connection was aborted by the software in your host machine

I'm trying to implement a live search through the jquery plugin Select2 in my Django 1.11.4 project. Running Python 3.6. When I type in the textbox, the server doesn't seem to be able to handle the number of requests and it closes, followed by these series of errors.
I've spent a couple hours following a couple threads on SO SO(more) , Google, etc but none have a working solution. I thought it was a python version issue, but I've upgraded from 2.7 to 3.6 and still have it. Any help would be great thanks!
This the view that's being called by the ajax call:
def directory_search(request):
# Query text from search bar
query = request.GET.get('q', None)
if query:
# Searches the DB for matching value
customers = Customer.objects.filter(
Q(name__icontains= query)|
Q(contract_account__icontains= query)|
Q(address__icontains= query)|
Q(address__icontains= query)|
Q(email__icontains= query)
).distinct()
# Turns queryset into dict
customers = customers.values("contract_account","name")
# Turns dict into list
customers_list = list(customers)
return JsonResponse(customers_list, safe=False)
else:
return JsonResponse(data={'success': False,'errors': 'No mathing items found'})
This is the js/ajax call for the Select2 plugin:
$(".customer-search-bar").select2({
ajax:{
dataType: 'json',
type: 'GET',
url:"{% url 'portal:directory_search' %}",
data: function (params) {
var queryParameters = {
q: params.term
}
return queryParameters;
},
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.name,
id: item.contract_account
}
})
};
}
},
escapeMarkup: function (markup) { return markup; },
minimumInputLength: 1,
templateResult: formatRepo,
templateSelection: formatRepoSelection,
language: { errorLoading:function(){ return "Searching..." }}
});

It seems to be a error on chrome. It didn't come to me, 'cause I was using Opera, but opera uses chromium as well. In internet explorer the error didn't show.

Authentication failed to connect to mongodb using pymongo

We have written a piece of code in python script using pymongo that connects to mongodb.
username = 'abc'
password = 'xxxxxx'
server = 'dns name of that server'
port = 27017

import pymongo
from pymongo import MongoClient
client = MongoClient(url, serverSelectionTimeoutMS=300)
database = client.database_name
data_insert = database.collection_name.insert_one({'id': 1, 'name': xyz})
When I tried to do these operations, it raises an error:

pymongo.errors.OperationFailure: Authentication failed.
In MongoDB, while performing queries we are getting the responses normally, without raising any errors.

Because the other answers to your question didn't work for me, I'm going to copy and paste my answer from a similar question.
If you've tried the above answers and you're still getting an error:
pymongo.errors.OperationFailure: Authentication failed.
There's a good chance you need to add ?authSource=admin to the end of your uri.
Here's a working solution that I'm using with MongoDB server version 4.2.6 and MongoDB shell version v3.6.9.
from pymongo import MongoClient
# Replace these with your server details
MONGO_HOST = "XX.XXX.XXX.XXX"
MONGO_PORT = "27017"
MONGO_DB = "database"
MONGO_USER = "admin"
MONGO_PASS = "pass"
uri = "mongodb://{}:{}#{}:{}/{}?authSource=admin".format(MONGO_USER, MONGO_PASS, MONGO_HOST, MONGO_PORT, MONGO_DB)
client = MongoClient(uri)
Similar fix for command line is adding --authenticationDatabase admin

Well, I have been stuck with the same error for almost 3-4 hours. I came across solution with the following steps:
from your shell connect to MongoDB by typing: mongo
afterwards, create a database: use test_database
Now create a user with the following command with readWrite and dbAdmin privileges.
db.createUser(
{
user: "test_user",
pwd: "testing12345",
roles: [ "readWrite", "dbAdmin" ]
}
);
This will prompt Successfully added user: { "user" : "test_user", "roles" : [ "readWrite", "dbAdmin" ] }
you can check by typing: show users.
It will also show you DB name you created before in the json.
now you should be able to insert data to your database:
client = MongoClient("mongodb://test_user:myuser123#localhost:27017/test_database")
db = client.test_database
data = {"initial_test":"testing"}
db["my_collection"].insert_one(data).inserted_id

I ran into this error, and my problem was with the password.
I had what I believe to be a special character in the Master account. Changing the password to be only alphanumeric fixed it for me.
Code snippet
client = pymongo.MongoClient(
'mongodb://username:alphaNumericPassword#localhost:27017/?ssl=true&ssl_ca_certs=rds-combined-ca-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false'
)
# Specify the database to be used
db = client['prod-db']
