I tried downloading this video locally on my machine so that I could upload to test, but I get an error that says "File Wasn't Available on Site" (unrelated to gifbuddy)
However, I did get a timeout error from the application because it took too long to return a response (the gif was still uploaded, but the user sees an error)
For my own knowledge:
Were you just trying to upload this video to get a nostr.build link?
Or did you want it broadcasted on nip94/more relays?
Or were you trying to meme it?
