Posting on Buy me a coffee?

Hello everyone. A very trusted site buymeacoffee.com, there is an option to post there. I posted, set the article settings to public, but if I go to the post URL from another browser without logging, it returns a 404 error for this URL. I'm wondering how to post there so that it is visible from the outside, and to Google bots. Has anyone successfully posted there? Most likely the problem is that I have not linked the payment to my account, but I can't do this, maybe there is another way to publish an article there so that it is visible from the outside?

Here is a post that's published visible to outside and is index by google.

May be analyze account and see why it got published?
