@tfarrington3d that updated error message is a change we recently deployed to provide additional context to users and a hint about what might be causing a problem.
We have been unable to reproduce the error, even with the files you have provided, on a number of browsers and operating systems. You should be able to successfully upload any WAV, MP3, OGG or FLAC file up to 100MB in size.
Are you able to test with:
- A different computer on the same network?
- A different account on the same computer? (user account and/or Syrinscape account)
- A different network (work, school, friend’s house)?
I believe the specific error you are seeing occurs when the browser refuses to even establish a connection for some reason. It seems odd that would be the case only for WAV files and not MP3.
One suggestion has been CORS (cross origin resource sharing) policy blocking the browser from making a connection from a page loaded on one domain to another resource on a different domain, hence my question about the domains being accessed in the network tab. We have had trouble in the past with cache data including links to a previously used server after reconnecting to a new server. That should no longer be an issue, but I have just cleared our cache for your account anyway to be sure.
