About the Tinyurl links... (Pixiv Fanbox)

Someone reported me that the latest TinyURL linking to the Ms. Fortune post didn't work and when I tried it myself, it gave me: "Error: Unable to find URL to redirect to." Oddly enough I had tested the URL link earlier and it had worked, and also all the previous links from other posts were just fine.

Then I tried switching from:

https://tinyurl.com/(MIXTURE OF LETTERS)

...to:

https://preview.tinyurl.com/(MIXTURE OF LETTERS)

i.e. Adding the "preview" to the URL link and it appeared to work again.

If this keeps up, I will simply use the "preview" version of the URL links and hope there won't be any issues anymore.

But I need feedback testing the URL links from you.
