I had to do a clean install of my OS on my iMac pro a few days ago and ever since I am no longer able to upload directly to vimeo from the Media Encoder. A feature I used multiple times a day without issues before.
The only error that shows on the Error Log is: Vimeo - Could not obtain upload ticket
I first contacted the people over at vimeo who told me to sign out and sign back in, he also told me that he "re-established your connection to Media Encoder on our side" whatever that meant.
The issue remained and according to them, it's on Adobe's side now, since there's nothing more they or I can do.
Any help will be appreciated.
Did you ever get an answer to this problem? I'm having it also, from multiple computers.
