Can you verify it works directly to nostr.wine?

Unable to broadcast to either filter or Nostr.wine
But you’re sure it works on damus and nos?
Actually have less time than I was expecting today but that seems very unlikely.
Selecting nostr.wine from the front page on blogstack pulls up posts, are these not on nostr.wine?
Hmm ok about to head out but from everything I can see your note is on nostr.wine.
Habla.news also shows the note was seen on nostr.wine:

Cool. Thanks for taking time to dig in. I wasn't able to post direclty to nostr.wine or filter.nostr.wine, though, when I tested a new note isolating for those relays. The previous notes were broadcast to other relays (and maybe also wine?)
Another thing it could be is total event size. We probably have lower limits than some.
Can you look in your browser console when you try to publish and see if you see a response from our relay? It should say why we are rejecting it.
