Sometimes an upload to Door43 from translationStudio fails. When this happens, there are several things to check.
1. Is the user logged in?
It is possible to be logged in as a local user, but forget this when it’s time to upload.
2. Is the Internet connection good?
translationStudio is pretty good at using a weak connection, but if it’s bad enough, it may not work. (It takes too long and the app stops trying.)
3. Authentication problems.
If you get an error message like Key content has been used as non-deploy key that probably means that the user should log out of translationStudio and log back in. This happens sometimes when the authentication between the server (Door43) and the app (translationStudio) get out of sync. (You may need to check the log to see the full error text. Please check the help document about checking the log.)
