010101 never seen that before.
It doesn't seem to be related to any kind of IP or geo block. I can access your website fine from any of my IPs.
However any request made with the Guzzle PHP library to that URL causes a 500 error π
$client = new \GuzzleHttp\Client()
$client->get('https://www.wilcosky.com/')
// GuzzleHttp\Exception\ServerException with message 'Server error: `GET https://www.wilcosky.com/` resulted in a `500 Internal Server Error` response
Looking at the body of the response, it seems to be an exception thrown by a Cloudflare Worker. The response includes "Worker threw exception" and "If you are the owner of this website: you should login to Cloudflare and check the error logs for www.wilcosky.com."
