Slow upload- XHR returned response code 0

Hi, I’m having a problem uploading several files to Axure share over the past weeks.

When I’m uploading via [] the message I’m getting is:
“XHR returned response code 0. Please contact us at if this problem persists.”

When I’m using the “Share” button on Axure RP 9, it gets to 100% upload quite fast, but then fails.

I tried several files, the largest is only 150 MB.

How can I solve it?

I’d do as it says email Axure at the address listed. I think you’ll probably get a quicker response that way. In my experience they’re very prompt via email.
