Resolution of problems Ethereum trading bot errors on Binance using Python and Websocket Connection

As automated trading robot developer running on Mac with VS code, you are not the only one to encounter problems that connect to the exchange of Binance through its websockets bees. The authorization of denied errors is common when trying to establish a connection between the code and the Exchange servers. In this article, we will walk through some steps to solve the problem and solve it.

Understanding the problem

The error message is permissionerror: [Erno 13] The authorization denied this indicates that the program is not able to obtain authorization to connect to the Binance or the websocket server. This may be due to several reasons, including:

• Inadequate authorizations on your computer system

• User account erroneously configured with insufficient privileges

• The binance bees key or access token is not set correctly

Problem resolution steps

To solve this problem, follow these steps:

1. Check the configuration of the binance and authorizations

Before connecting to Exchange’s API, make sure you have:

• An API key of valid binance (ID API) and access token

• The type of correct account (e.g. binance rest bees)

• The correct user role in the account settings

You can find these details on the platform [Binance Developer] (

2. Check your Python environment variables

Make sure that the following environment variables are set correctly:

• Path: focus on the directory containing your Python interpreter

• Useer ': specifies the access credentials of the current user (not necessary for this step)

• Binance_api_Keyis binance_access_tken: Sets these variables with the Binance API key and the access token

It is possible to check the variables of the environment by performing:

`Bash

Python -C “Import OS; Print (Os.environ [‘path’])”

`

3. Check the authorizations of the user account

In the VS code, go to
settings (Ctrl+Shift+P or CMD+Shift+P), select
Python , then click on the project
: [Project Name] Card. Search for the "execution" section and make sure that your user account has sufficient authorizations.

4. Check the version and interpreter of Python

Make sure to use the latest version of Python (3.9 or later) with the correct interpreter. You can check it by performing:

Bash

Python -Nersion

`

5. Reconfigure Binance API and Websocket Connections

If the above passages do not solve the problem, try to reconfigure Binance's bees and websocket connections:

* Binance Api : Update yourBinance.pywith the API key and access token.

* Binance Websocket : Make sure to install the correct library (for example,pybinance pypi-binance) and configure it correctly.

6. Check the websocket connection

Use an instrument as a curl to test the websocket connection:

`Bash

Curl -x post \

\

-H ‘Content-Type: Application/Json’ \

-D ‘{“symbol”: “btcusdt”, “type”: “limit”, “limit”: 10}’

Replace with the API key and the access token
