Python Requests Post Max Retries Exceeded with URL

As someone who has worked with Python and its Requests library, I have encountered the "Max retries exceeded with URL" error while sending a POST request. This error message is usually caused by either server-side issues or client-side network problems.

Causes of the Error

  • Server-side issues: If the server that you are trying to connect to is down, overloaded, or experiencing some other kind of issue, the request may not be able to establish a connection, resulting in the "Max retries exceeded with URL" error.
  • Client-side network problems: If there are any issues with your network connection, such as a slow or unstable internet connection, your client may not be able to establish a connection with the server and may result in the same error.

Solutions to the Error

If you encounter the "Max retries exceeded with URL" error, there are some steps you can take to solve the problem.

1. Check the server-side issues

If you suspect that the error may be caused by server-side issues, you can try to check if the server is up and running. You can also try to contact the server administrator to see if there are any issues on their end.

2. Check the client-side network problems

If you think that the issue may be caused by network problems on your end, you can try to check your internet connection. You can also try to restart your modem or router, or try connecting to a different network to see if the issue persists.

3. Increase the number of retries

If the issue persists, you can try to increase the number of retries in your request. This can be done by setting the "max_retries" parameter in the "Session" object.


import requests
from requests.adapters import HTTPAdapter
from requests.packages.urllib3.util.retry import Retry

retry_strategy = Retry(total=5, backoff_factor=1, status_forcelist=[ 500, 502, 503, 504 ])
adapter = HTTPAdapter(max_retries=retry_strategy)
session = requests.Session()
session.mount("http://", adapter)
session.mount("https://", adapter)

response = session.post(url, data=payload)

The above code block sets the "max_retries" parameter to 5 and defines a custom retry strategy to handle certain HTTP status codes. This should help you avoid the "Max retries exceeded with URL" error.

4. Use a different HTTP library

If all else fails, you can try using a different HTTP library, such as urllib or http.client. These libraries may have different behavior when handling network errors and may provide a workaround for the issue.
