I'm uploading an 11mb app (it's an ubuntu phone html5 app) to https://myapps.developer.ubuntu.com and then uploads to 100% and starts again to 100% and finally appears this error:

""The submitted files could not be uploaded, please try again.

Please include the following information when reporting this issue:

CONTEXT: onUploadFailed STATUS_CODE: 400 RESPONSE: {"successful": false, "errors": {"timestamp": ["Timestamp is expired."]}} "" I've tried again and again with same result, using other browsers and other networks. I can upload other apps (I've tried to upload a webapp and I can upload it).

  • I just tested uploading a file myself and it's fine. Maybe try again now?

  • Seems your file is obviously way bigger than mine which might be why yours fails and mine succeeds. After how long does it fail?

    Today. It works now using fast network, with slow network fails... if upload needs one or more minutes then fails.

  • Spoke to the developers and they're working on a fix which extends the timeout. Thanks for reporting the issue!

    I've been told that a workaround has been rolled out which should prevent this happening. It will still fail if your upload takes a very long time.
