Looks like it still is encountering problems, I get a 403 error from London an ny. Might be cloudflare blocking it?
If it is yours, thanks for reporting it, I have pushed the fix down the pipeline. Its not giving a 403 anymore, but still doesn't render properly.
I have tried to debug it with a different engine but it looks like the site has JS based browser detection (not based on user agent strings). Since its a headless browser, some JS functionality is unavailable, and super dynamic sites break. Another limitation I am working around.
