"404. That’s an error." Message for privately published extension

[John]

It has been about 2 hours now. The strange thing is that I can access it in one browser, but not another. I'm logged with the same google account in both browsers, and I tried clearing cookies several times. Everyone else who has tested the URL gets nothing but 404s.

Hi John,

Have you tried to delete your browser cache? Or tried to create a new Chrome user profile?

Thanks,

Yes. I ended up republishing as unlisted.

Hi John,

That is good.

It should normally work if using Private visibility: Trusted testers:
