Hello! We have a problem connecting to our App Search engine from python using the elastic\_app\_search library. After creating a client instance with our proper credentials the server is rejecting to output anything. For illustration I am using the get\_schema method. ```auto from elastic_app_search import Client client = Client(base_endpoint=base_endpoint,api_key=api_key, use_https=False) engine_name = "our_engine" client.get_schema(engine_name) ``` We get the following error: ```auto HTTPConnectionPool(host='https', port=...): Max retries exceeded with url: //... /our_engine/schema (Caused by NewConnectionError(': Failed to establish a new connection: [Errno -2] Name or service not known',)) ``` Is there anything we need to adjust in the App search settings to allow it? We should definitely not exceed any limit as we were not connected never before. The weird thing is that from javascript the connection works fine. Thank you! ---

Hello @rishelini The error tells about the fact the domain cannot be resolved (`Name or service not known`). The documentation at this link [https://github.com/elastic/app-search-python/blob/master/README.md](https://github.com/elastic/app-search-python/blob/master/README.md) Can you please check the value of `base_endpoint` doesn't contain `http://` or `https://`? Also, does the host where the python code runs has access to the endpoint? Can you try with a `curl`? ---

Hello @Luca_Belluccini, so I removed the `https://` part from the endpoint, that was probably the cause. But ended up with another exception `elastic_app_search.exceptions.NonExistentRecord`. Is it good? With **curl** I was able to reach the endpoint in `https://` format with response "You are being redirected" to the login page. Thank you for your help! ---

> [@rishelini](#): > > so I removed the `https://` part from the endpoint, that was probably the cause. But ended up with another exception `elastic_app_search.exceptions.NonExistentRecord` . Is it good? I think you managed to connect. Which one of the methods generated the exception `elastic_app_search.exceptions.NonExistentRecord`? ---

The methods I am calling on the Client instance - list\_engines, create\_engine, get\_documents. In App Search, everything is set up and the engine whose name I am passing to the client contains data which I put there as a json file. I am pretty sure I am entering right engine name - the one that is displayed in App Search under Engines. ---

Just to clarify: 1. If your `base_endpoint` is HTTPS, set `use_https=True` in the `Client` initialization. 2. If you are using the [SaaS version available on swiftype.com](https://app.swiftype.com/as) of App Search, you should use the version 7.5.x of the client. 3. Checking the code, the only way to get `NonExistentRecord` is when the request returns HTTP 404. As the library uses `requests` library, if you're using Python 3, you can add this at the beginning of your script to log the requests (from [StackOverflow](https://stackoverflow.com/questions/16337511/log-all-requests-from-the-python-requests-module?rq=1)). Some details will be in `requests.log`, others in `stdout`. ```auto import requests import logging from http.client import HTTPConnection log = logging.getLogger('urllib3') log.setLevel(logging.DEBUG) fh = logging.FileHandler("requests.log") log.addHandler(fh) HTTPConnection.debuglevel = 1 ``` ---

1. Yes, I am using this setting 2 . As for the elastic\_app\_search library, I'm using version 7.6.0. After I added your script, I found this in the `requests.log`: ```auto https://my_base_endpoint:443 "GET /engines/our_engine/schema HTTP/1.1" 404 636 ``` When I click on this URL it takes me to the login page and after that on the page with schemas. Still, really don't know where the problem is. ---

What is the result of `client.list_engines(current=1, size=20)`? Does `our_engine` contains any special character? (I am not able to tell if this is the actual engine name or you've hidden the engine). ---

Make sure your base\_endpoint looks something like this, excluding the protocol and including `/api/as/v1` [77b18391238412934827.app-search.us-east-1.aws.found.io/](http://77b18391238412934827.app-search.us-east-1.aws.found.io/) **api/as/v1** ---
