How to fix SSLError in Python requests?

---

If you encounter an SSLError while making requests in Python, it usually means that the SSL certificate verification has failed. This can be due to a variety of reasons, such as an expired or invalid SSL certificate, an incorrect system time, or a server misconfiguration. Here are some steps you can take to fix the SSLError in Python requests:

Step 1: Verify the SSL certificate

The first step is to check if the SSL certificate is valid and not expired. You can verify this by opening the URL in a web browser and checking the certificate details. If the certificate is invalid or expired, contact the website administrator to get it updated.

Example:

import requests

 

url = "https://www.example.com"

response = requests.get(url)

 

# Check if SSL certificate verification failed

if response.status_code == 200:

    print("Request successful!")

else:

    print("SSL certificate verification failed.")

2. Disable SSL certificate verification:

If you’re sure that the website is secure and you want to ignore SSL certificate verification, you can disable it by adding verify=False to the requests.get() method. However, this is not recommended as it can compromise the security of your application.

import requests

url = "https://www.example.com"
response = requests.get(url, verify=False)

# Check if SSL certificate verification failed
if response.status_code == 200:
    print("Request successful!")
else:
    print("SSL certificate verification failed.")

3. Set the system time correctly:

An incorrect system time can cause SSL certificate verification to fail. Check that the system time is set correctly and synchronize it with an NTP server if necessary.

import requests
import datetime

# Check the current system time
current_time = datetime.datetime.now()
print("Current system time:", current_time)

url = "https://www.example.com"
response = requests.get(url)

# Check if SSL certificate verification failed
if response.status_code == 200:
    print("Request successful!")
else:
    print("SSL certificate verification failed.")

4. Upgrade requests library:

If you’re using an outdated version of the requests library, upgrading it to the latest version may fix the issue.

pip install –upgrade requests

5. Add SSL certificate to the trusted list:

If the SSL certificate is self-signed or not trusted by default, you can add it to the trusted list by using the certifi module. You can download the certificate and save it to a file, then pass the file path to the verify parameter in requests.get() method.

import requests
import certifi

url = "https://www.example.com"
certificate_path = "/path/to/certificate.pem"

response = requests.get(url, verify=certificate_path)

# Check if SSL certificate verification failed

if response.status_code == 200:
    print("Request successful!")
else:
    print("SSL certificate verification failed.")

6. Check proxy settings:

If you’re using a proxy server, make sure the proxy settings are correct and the server is running.

import requests

url = "https://www.example.com"
proxies = {"http": "http://proxy.example.com", "https": "https://proxy.example.com"}

response = requests.get(url, proxies=proxies)

# Check if SSL certificate verification failed
if response.status_code == 200:
    print("Request successful!")
else:
    print("SSL certificate verification failed.")

By following these steps, you should be able to fix the SSLError in Python requests and continue making secure HTTP requests.
