Introduction
Python Requests is one of the most popular libraries for sending HTTP requests in Python. It allows you to send HTTP/1.1 requests easily and integrates well with Python’s built-in modules.
However, it can be frustrating when your Requests.get() function always returns a 404 error. In this article, we’ll explore 10 possible reasons why this may be happening and how to fix the issue.
Reason #1: Invalid URL
The first reason your Python Requests.get() may be returning a 404 error is that the URL you’re trying to access is invalid. For example, if you forget to include the http:// or https:// at the beginning of the URL, requests will not be able to find the page and will return a 404 error.
To fix this, make sure that you have included the protocol in the URL and that the URL is spelled correctly.
Reason #2: Incorrect Headers
Another reason why Requests.get() may return a 404 error is that the server requires certain headers to be included in the request. For example, some servers require a User-Agent header to be included in the request, which identifies the client making the request.
To fix this, you can add headers to your request using the headers parameter in Requests.get(). For example:
import requestsheaders = {'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}response = requests.get('https://example.com', headers=headers)This will send the User-Agent header along with your request and may resolve the 404 error.
Reason #3: Server-side Error
It’s possible that the page you’re trying to access is actually experiencing a server-side error, such as a 500 Internal Server Error. In this case, there’s nothing you can do on your end to fix the issue – it’s up to the server administrator to resolve the error.
You can verify if this is the case by attempting to access the same URL in a web browser. If you also receive a 404 error, the server is likely experiencing an issue.
Reason #4: Missing Authentication
If the page you’re trying to access requires authentication, such as a login page, you may receive a 404 error if you haven’t included the necessary credentials in your Requests.get() call.
You can add authentication credentials using the auth parameter in Requests.get(). For example:
import requestsauth = ('username', 'password')response = requests.get('https://example.com', auth=auth)This will send the provided username and password credentials along with your request.
Reason #5: Incorrect HTTP Method
If you’re trying to perform an action on a page, such as submitting a form, you may need to use a different HTTP method than GET. For example, a form submission typically uses the POST method.
To specify a different HTTP method, you can use the method parameter in Requests.request(). For example:
import requestspayload = {'username': 'bob', 'password': '12345'}response = requests.request('POST', 'https://example.com/login', data=payload)This will send a POST request with the specified payload data.
Reason #6: URL Redirects
If the URL you’re trying to access redirects to a different URL, you may receive a 404 error if Requests.get() isn’t set up to handle redirects by default.
You can enable redirection handling in Requests by setting the allow_redirects parameter to True. For example:
import requestsresponse = requests.get('https://example.com', allow_redirects=True)This will follow any redirects encountered when attempting to access the specified URL.
Reason #7: Invalid SSL Certificate
If the server you’re attempting to access uses SSL encryption, your Requests.get() call may return a 404 error if the SSL certificate is invalid or expired.
To bypass SSL certificate checking, you can set verify to False in the Request.get() call. However, this is not recommended – it’s better to obtain a valid SSL certificate for the server you’re accessing.
Alternatively, if you have a valid SSL certificate for the server, you can pass the path of the certificate file to the cert parameter in Request.get(). For example:
import requestsresponse = requests.get('https://example.com', cert='/path/to/certificate.pem')Reason #8: Timeouts
If the server you’re attempting to access is slow to respond or experiencing a high volume of traffic, Requests.get() may time out and return a 404 error.
You can increase the amount of time Requests waits for a response by setting the timeout parameter. For example, to wait 5 seconds:
import requestsresponse = requests.get('https://example.com', timeout=5)Reason #9: Rate Limiting
If the server you’re attempting to access has rate limiting in place, you may receive a 404 error if you exceed the allowable request rate.
To avoid this, make sure you’re not sending too many requests in a short period of time. You can also implement a delay between requests using the time.sleep() method.
Reason #10: Content-Type Mismatch
If the server you’re accessing expects a certain Content-Type header in the request and you don’t include it, you may receive a 404 error.
You can include the Content-Type header using the headers parameter in Request.get(). For example:
import requestsheaders = {'Content-Type': 'application/json'}response = requests.get('https://example.com', headers=headers)Conclusion
There are many reasons why your Requests.get() call may be returning a 404 error. By understanding these possible causes and using the appropriate solutions, you can save yourself time and frustration when working with Python Requests.

A 404 error occurs when a server cannot find the requested URL. It usually means that the page or resource does not exist.
There could be several reasons for this, including incorrect URL, server issues, authentication problems, and session issues.
You can try opening the URL in your browser to see if it loads properly. Alternatively, you can print the URL in your Python code to make sure it is correct.
You can try using a different HTTP library, such as urllib or httplib. You can also check if the server is running properly and if there are any authentication or session issues.
You can try pinging the server or using a tool like cURL to check if the server is responding to requests.
Authentication issues occur when a user does not have the proper credentials to access a resource on the server.
You can try passing the correct username and password as parameters in your Python code. You can also try using a different authentication method, such as OAuth.
Session issues occur when there is a problem with the session ID or cookie that is being used to authenticate the user.
You can try resetting the session ID or cookie in your Python code. You can also try using a different session management method, such as tokens.
You can try contacting the server administrator or the API provider for further assistance. They may be able to provide additional information or fix the issue on their end.
