getting an error 502 bad gateway

[adirzoari]

Hey, I'm using selenium-wire, when I open my website, I'm getting TlsProtocolException('Cannot establish TLS with xxxxxxx (sni: xxxxxx): TlsException("SSL handshake error: Error([(\'SSL routines\', \'\', \'unsafe legacy renegotiation disabled\')])")').. when I open the same website without selenium-wire, just with selenium, it works fine..

the website url is https and I have valid certificate and connection is secure.

    from seleniumwire import webdriver

    chrome_options = Options()
    chrome_options.add_experimental_option("detach", True)
    chrome_options.add_argument("--start-maximized")
    chrome_options.add_argument('--auto-open-devtools-for-tabs')
    chrome_options.add_argument('--log-level=2')
    chrome_options.add_experimental_option('excludeSwitches', ['enable-logging'])
    chrome_options.add_argument("window-size=1280,720")
    chrome_options.add_argument('--disable-dev-shm-usage')
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument("--disable-extensions")
    chrome_options.add_argument("--disable-setuid-sandbox")
    chrome_options.add_argument("--ignore_ssl")
    chrome_options.add_argument("--dns-prefetch-disable")
    chrome_options.add_argument('ignore-certificate-errors')
    capabilities = DesiredCapabilities.CHROME
    capabilities["goog:loggingPrefs"] = {"performance": "ALL",'browser':'ALL','server':'ALL'}  # chromedriver 75+
    capabilities['extendedDebugging'] = True
    capabilities['acceptSslCerts'] = True
    capabilities['acceptInsecureCerts'] = True
    capabilities['PageLoadStrategy'] = None
    selenium_options = {
        'verify_ssl': False,
        'connection_timeout': None,
        'backend': 'mitmproxy'

    }
    driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=chrome_options,desired_capabilities=capabilities,
                              seleniumwire_options=selenium_options)

    driver.get(os.environ['URL'])

Thanks for raising this. It looks like the error is related to OpenSSL which selenium wire uses behind the scenes.

This SO suggests a workaround. Perhaps you could give that a try?

@wkeeling Hey, I restarted my pc and still have the same issue.. when I run pip install cryptography it shows me

I have openssl latest version.. what I can do?

options = ChromeOptions()
options.add_argument('--no-sandbox')
options.add_argument('--single-process')
options.add_argument('--disable-dev-shm-usage')
options.add_argument("--start-maximized")
options.add_argument('--auto-open-devtools-for-tabs')
options.add_argument('--log-level=2')
options.add_argument('--disable-features=IsolateOrigins,site-per-process')
options.add_argument("--ignore_ssl")
options.add_argument('--ignore-ssl-errors')
options.add_argument('--ignore-certificate-errors')
options.add_argument('--allow-insecure-localhost')
self._driver = webdriver.Chrome(options)

Adding the argument below when initiating a driver works for me. I'm using seleniumwire-5.1.0 and firefox-114 in docker. I also downgraded cryptography to 36.0.2 and pyOpenSSL to 22.0.0.

capabilities={"acceptInsecureCerts": True}
