Resolved.
I checked the “Display in public lists” box in Advanced Settings.
It might have been better to notify users when there are changes to the settings. If someone hadn't notified me, I wouldn't have noticed it right away.

Hi,
I ran some tests on different browsers before posting here.
My comic only works if you're logged in; if you send the link to an external user, the message: “Comic Not Found” or "Something went wrong..." appears. Have the rules changed, or is this a bug?
This issue has been happening for some weeks or so—at least that’s when I was notified.
Thank You.
