repository export not working

Exporting a project from is broken. Clicking on export, I’m receiving a notification in the web ui that the export has been started and that I’ll receive a mail with a download link. I’ve been trying this for weeks but never received a mail (i checked the junk).

Gave it another try yesterday, but again received no link. Does this work for anybody at all?

Tried again, didn’t receive a mail again. Note: I regularly receive notification mails from that repo/ Any idea?
