More Siteground/Elementor/Claude issues

I actually have gotten very close to getting OAuth working by disabling all plugins (including SG Security), changing templates, adding the cloudflare header transform rule,.  All the curl requests seem to be returning properly (except that I see content-type i still text/plain and i think that should be returning json? Not sure.  I even had OAuth connected!

But then I started to add plugins back (retrying the connection after each time).  Somewhere along that way, I am now at the point when I try to connect and it pulls up your authorization window – it is not writing the URL properly (see the two https’), and if I delete one of them so the URL is correct, it goes back to failing the connection – on a completely barebones / no plugins installed wordpress instance.  AHHHHHH. Oh and I was never successful with the API KEY method thus far after creating the JSON file and working with support back and forth multiple times until they stopped responding. Cant seem to get claude to read the JSON file which was confirmed to be correct. Anyhow, Ive gotten closer with OAuth than the API KEY method oddly is kind of my point.
