I was just trying to upload a decent-ish sized snap to the store and got this proxy error. A previous thread suggested this had been fixed. Is this a new issue or recurrence of the previous one?
Also, echoing HTML at me isn’t a nice developer experience.
$ snapcraft push shattered-pixel-dungeon_0.6.3_i386.snap --release stable
