Cannot upload images to Leo

I’m trying to get an image translated by Leo, it’s a 633.1KiB PNG file. I keep getting “There was a network issue connecting to Leo. Check your connection and try again.” and I checked with net-export and the actual error seems to be “Server reset stream.” I get the same error if I try to screenshot the image as a page. Even a 267.7KiB PNG fails.

Is image uploading to Leo completely broken?

Version 1.80.113 (and also tries 1.80.114, still the same issue there as well).

It’s working now for at least one day.
