Export project emailed link doesn't work (404)


Using gitlab 8.9.6 CE. I choose a project and export it. I get an email with a link to download the project tar file but when I click on it it get an immediate 404 not found.
The URL for the 404 is https://gitlab.my.domain/mynamespace/myreponame/download_export

Appreciate suggestions about why this might be happening or how to troubleshoot.



Responding to my own post. Solved. I found that for some reason the state of the session had become confused and the redirect that results from clicking the link caused the sign-in page to download as a file rather than load as a page. Deleting the cookie from the browser fixed the problem.
