[Python] TLS Verification Error (x509: certificate signed by unknown authority) with...

I’m trying to use tls_client in Python to access https://www.google.com/ through a Bright Data residential proxy, but I keep getting an SSL verification error: tls: failed to verify certificate: x509: “*.google.com” certificate is not standards compliant. I want to either fix the SSL issue or safely bypass verification to make this work.

My Code


from tls_client import Session

proxy = "http://brd-customer-hl_37d678eb-zone-residential_proxy1:nbm6n6cp6qir@brd.superproxy.io:33335"
session = Session(client_identifier="chrome_114")
session.proxies = {"http": proxy, "https": proxy}

try:
response = session.get("https://www.google.com/")
print(response.status_code)
except Exception as e:
print(f"Error: {str(e)}")

Output


Error: failed to do request: Get "https://www.google.com/": tls: failed to verify certificate: x509: “*.google.com” certificate is not standards compliant

Details

• Python: 3.10
• tls_client version: [run pip show tls_client and add it here, e.g., 0.1.8]
• OS: macOS
• Proxy: Bright Data residential proxy (http://brd-customer-hl_37d678eb-zone-residential_proxy1:nbm6n6cp6qir@brd.superproxy.io:33335)

What I Tried

1. Setting session.verify_ssl = False—no effect, same error.
2. Using session.get(..., insecure=True)—fails with TypeError: get() got an unexpected keyword argument 'insecure'.
3. Tested the proxy with requests and verify=False—it works fine, but I need tls_client for its TLS fingerprinting.
