I noticed the FA 'shortens' the link, and if I go to the reply section I can copy and paste the 'full' link to the url for it to work.
idk if that's a solution but just something that has worked for long links that get shorted in the message.
Though idk if its a different issue for you (sorry in advance)

Yes that's the thing I also noticed. Looks like links will be shortened only if they will be send through Note.
But it's weird, I didn't have this problem earlier, even though links were shortened. And I tested this through email and DA, no problems there.

Youre not the only one, other artists is having the same problem.

Ah, I see.
Just hope there willl be solution to fix this problem. Though I've seen Drobox as one of the greatest place to send files.

I can only think of the following:
Did you clicked share before copying the link? I had once the mistake that I just clicked on copy link, but only I was able to see it. When I click on share and then copy link, it was working normally.

But I don't really know, maybe its a different issue I haven't encountered so far.

I clicked share, and there I saw copy link, I clicked it, but still says error :(

Sorry to hear that. I am still confused why it is not working and hope it will be resolved very soon.

These temporary solutions may not work for you, but I have noticed two things:

Firstly, any links from dropbox through fA seems to work through the app it seems. I never received the error with other artists, could be something to look into if your clients have access to that.

Secondly, when it came down to images at the very least, the link has something like this inside it: "amp;". After removing that small bit from the link, I was able to access the link without the error, but I'm unsure if this temporary workaround is just for image files, or can work for other files. The "amp;" appears multiple times on the link but if you remove it, you should be able to access the link again.

Yes, I checked and with app links work just fine.
And I saw this amp thing in the link, when I copy link it's not there until I send it to customer, then amp appears there. No idea why it does this, though.

Okay, link will work fine when I remove "amp;" from it (it appears 2 times there).
I think I can get it work like this,I just need to do instructions for customers while sending links through DB.

Glad I could be of some help, and that shouldn't be too hard.

"As of now Dropbox and FurAffinity have a sort of issue with shortening links. For now, right click the link and "Copy Link" and paste it into another tab and remove "amp;" on the web address. "amp;" may appear multiple times on the URL, so please be wary." :>

Whenever I send links to people, I usually see if it works on people's end, before I would go back and fix the link. Whereas if I do it through email or on chatting platforms like telegram and discord, I don't have problems there. Interesting to note how dropbox doesn't work for some people...Very weird.

Either the link was altered when added to whatever platform you have it in, or the platform is altering the link when displaying it to the user. I would click the link so it brings you to the 400 error page, then copy and paste the URL from address bar into a text file, then paste the URL that you know works and compare the two.
Like some sites will add an amp after any & in the link and that can "break" it for some people's computers.
