Url shortener doesn't work

[core01]

This code

$botan->shortenUrl($url, $userId);

returns:
{"status": "bad request", "info": "Error 111 connecting to ec2-52-91-171-196.compute-1.amazonaws.com:6379. Connection refused."}
Also in Web browser - https://track.botan.io/s/?token=SUPERTOKEN&url=%22https://google.com/%22&user_ids=1111111111

The same issue for me

[martosaur]

Same here, getting redirected from https://track.botan.io/s to http://track.botan.io/s with 404 🤷‍♂️
Is this product even supported?
