HTTP 403 during auth

[Hello1024]

It seems lidl's CDN is blocking python connecting.

Note that accessing the same URL from a browser works fine. Taking the headers from the browser and running the request via cURL doesn't work. Running the request via wget works. Changing user agents doesn't seem to solve it.

TL:DR: This is probably some tls fingerprinting level anti-bot protection. It's hard to bypass. Search 'AkamaiGHost 403' on Google to find others with the same issue. I tried some of the proposed fixes with no luck.
