I keep getting a 504 error when I try to upload a new version of my Add-on:

Hey @getmatlock! We had some issues with yesterday’s update to [addons.mozilla.org](http://addons.mozilla.org) that might have caused this error.

Can you try this again and let us know if you can submit an update?

I tried a few times, and maybe the 6th time around, it was able to be uploaded successfully!
