Generic Exception: Error: (404)

A member of my field team is unable to upload 12 surveys despite successfully submitting 15 at a similar time. The surveys which we cannot upload remain in the ‘Send Finalised Form’ tab with a message reading ‘Sending Failed’.

We have double checked the server info, internet connection and the date on the device being used but are still having issues.

Exact error message reads: Error: Generic Exception: Error: (404) at https://kc.kobotoolbox.org/kobodemouser/submission?deviceID=collect%3AQTX9fNxlxi7hSbYP
