Quite a few users have have reported that their Vimeo galleries have suddenly stopped working. The common error message seems to be

The oauth_signature passed was not valid

The short answer is that I have no explanation why so many signatures would immediately (and concurrently) go bad. It’s definitely an issue on Vimeo’s end, as thousands of TubePress-based Vimeo galleries continue to operate normally.

Until we get a final resolution, here are some steps you can take right now:

  1. Post a comment in the Vimeo API forum, particularly you can add on to this existing thread. The more users that post here, the faster we can get Vimeo’s attention.

  2. Try the troubleshooting steps in the TubePress documentation at Troubleshooting > Server-side > Vimeo OAuth. YMMV.

  3. Star this issue to track updates to the problem. I’ll be posting updates here as I get them.

With luck we should be able to get Vimeo’s attention and get a fix out shortly.
