Yesterday afternoon we added Twitterbot and and also removed the character encoding from the content-type header. Doesn’t seem to have made any changes.
As you mentioned, thumbnails are showing up for some tweets – maybe it has something to do with the size of the player?
Hey Jon, any chance you’ve gotten a moment to take a look now that we’ve edited the robots.txt file? Thanks!
Hoping for an update here. Any thoughts Jon?
Any chance you’ve heard back from the engineering team about this yet Jon?
Hi Andrew and Mikey, apologies again for missing these responses. I just responded to Andrew’s other discussion thread to send me a DM so we can set up a call to debug and resolve ASAP.

Hey guys, any idea on how to resolve this?
Our twitter looks awful without nice thumbnails
Many thanks
Geraint
Hi @UNIT9, this issue was resolved back in August, but never closed out. Could you point me to a URL where you are experiencing an issue with Vimeo thumbnails?

@jbulava On our twitter - @UNIT9
We are trying to post John Frieda Behind The Scenes Teaser on Vimeo
But the thumbnail just comes up as black…
I was underground and could not answer as quickly 
I’m seeing the same behavior, but I’m only seeing it for this specific video. Do you own this video? I’m curious to know if the thumbnail was updated after the upload. It’s possible that if the original thumbnail for the video was just a black screen that that is what we are caching on our side to render the card. I’m looking into this further and looping in the Cards engineering team, although they are in San Francisco so a response may be later today.

@jbulava That’s great, thanks!
Yeah we own the video - the original thumbnail would have been
just a clip from the video had it have been changed - it would
never be just black. Let me know if they get back to you!
My direct email is geraint.smith@unit9.com
Thanks a lot!

Ok, great. I’ll respond here with any updates.
Hey Geraint, the engineering team confirmed that there was some kind of failure with our image fetcher when this specific Card was created. The Card for John Frieda Behind The Scenes Teaser on Vimeo should now render correctly. Please confirm when you get the chance!

Hi mate, it works now thanks!
I need this one too 
Skrillex - Doompy Poomp Mashup on Vimeo
Would I have to do this every time??
You shouldn’t. I’ll submit this to the team as well. They are trying to track down a pattern for Cards that have failed, so this will definitely help their cause.
The second video should be working now as well.

@jbulava Hi mate, thanks for your help
It’s not unfortunately
Sorry about that. I should have checked it myself! I have made this known.
There’s also a fix for the wider issue currently being reviewed. I’ll be sure to post here when it’s shipped! (Internal reference is PREL-12449)
is there any hotfix for the moment? we are promoting our kickstarter campaign and not having the video thumbnail is a bit annoying (it need to draw people in!), as you can see here: https://twitter.com/UntilDayBreaks
these 2 videos are being affected so far:
if you could at least fix the trailer one quickly that would be great!
thanks for looking into this guys!
Sorry for the delayed response, Jack. This was made a top priority last week, but the fix was within our storage infrastructure and needed to undergo quite a bit of testing. It has passed these tests and should go into production this week. Apologies for the inconvenience this has caused the KickStarter campaign. On the plus side, I just pledged £10.00 myself!
thank you! i appreciate your update! i know you guys do a good job of keeping on top of things.
apparently the problem is only happening on the one trailer video now. we have a few other videos now we are sharing so all is not lost!! could you give me a shout when the fix goes live or something?
thanks so much for backing too! i hope it’s because you think our project is AWESOME! i know you guys are!
cheers
