As an example, if I go to the starting guide and click on the top comment, I get the following response:

“This site can’t be reached The webpage at https://lemmy.world/comment/97159 might be temporarily down or it may have moved permanently to a new web address. ERR_INVALID_RESPONSE”

Dev tools shows response code: 400 (from service worker) for this request.

I don’t see this behavior on every single comment link, but it shows up for a lot of them, seemingly randomly.

I see it across different browsers and normal vs. incognito mode.

Any clues on what’s broken?
