As an update here -- this seems to happen the most when connected to Xfinity (Comcast) internet. When I switch to my T-Mobile phone hotspot, it goes through fine every time.

This is still happening. I have to try to re-upload many, many times. Constantly get a "bus error".  ~/Code/IntoTheDawn/ [main*] xcrun notarytool submit /Users/jh/Code/IntoTheDawn/Builds/IntoTheDawn-0.3-build.3-macOS.zip --keychain-profile jamonholmgren Conducting pre-submission checks for IntoTheDawn-0.3-build.3-macOS.zip and initiating connection to the Apple notary service...

When I tether, it works (very slowly), but this seems untenable long-term. Surely there's some way to make this CLI more robust?

I am running into this same issue here almost a year later in March 2025, and it's driving me nuts. This happens at different chunk numbers at different times, and sometimes (rarely) succeeds just fine. Any other ideas?
