Getting 502 Bad Gateway Error with LunaProxy and Selenium Wire

[Austin Norman]

I hope you're doing well. I'm trying to automate form submissions on "https://securelastexpense.com" using a Python script with Selenium Wire and LunaProxy, but I'm encountering a 502 Bad Gateway error. The error appears to be related to a TLS/SSL handshake failure, as shown in the browser logs (e.g., TlsProtocolException('Cannot establish TLS with securelastexpense.com:443...')). I've tried updating the cryptography library and setting verify_ssl=False in Selenium Wire options, but the issue persists.

I’d appreciate any help to resolve this. Thank you!

Selenium Wire is outdated, unmaintained, and unaffiliated with the Selenium project. I'm not surprised it has issues, but you are sort of on your own with that.
