[varsh...@gmail.com]

Hello Everyone,

I am new to Mongo db and I am tryign to pull the files out of Mongo DB using python Scripts.

 I am using RoboMongo as my client and connecting to a remote server from robo mongo.

When I am trying to execute the scripts,It is giving me an Error of Server Selection Timeout and I dont understand how to rectify it.

Can you please help me of how to get rid of that error.

ServerSelectionTimeoutError: localhost:27017: [Errno 10061] No connection could be made because the target machine actively refused it




Mycode



import pymongo
from pymongo import MongoClient
Client = MongoClient()
mydb = Client.DEFI
mycollection = mydb.defi_test
items = mycollection.find({})
print items
for document in items:
       print(document)

You say "connecting to a remote server" but your code reports "localhost:27017"  which is the default for MongoClient. Supply an appropriate hostname to MongoCLient

I tried it but it throws me the same error.

Hi

When I am trying to execute the scripts,It is giving me an Error of Server Selection Timeout and I dont understand how to rectify it.

ServerSelectionTimeoutError: localhost:27017: [Errno 10061] No connection could be made because the target machine actively refused it

That error is typically caused by trying to connect to a server that either has no MongoDB running, or the port is being blocked by a firewall. Could you please check that MongoDB is running, and you can connect to it using the mongo shell?

Also, this part in the code you posted:

Client = MongoClient()

Means that MongoClient will attempt to connect to localhost:27017 by default (see Pymongo MongoClient default values) as Rhys has mentioned. Have you modified the MongoClient() setting to point to the relevant server?

I tried it but it throws me the same error.

Could you post what you have tried and the error you see?

Best regards,
Kevin
