This answer is not answering the question. This answer attempts to remedy the error shown in the question. While I agree that this might beneficial to someone googling the error message, this doesn't answer the question.
What to do with this answer? Flag and delete it? Downvote it? Or just leave it alone?
If I was in OP's situation, having someone help interpret the error could be useful. So you're right in that it doesn't answer the question but does point OP in the direction of "nothing's listening on port 80" which would make sense if everything was forklifted to https on 443, but this script simply wasn't updated.
However, something else changed the path, possibly at the same time or maybe completely unrelated. This could appear in other places on the same host in the future.
If you think the answer is wrong, comment and downvote. IMO it is not irrelevant, and could definitely help someone in the future.
Headers and bodies on good questions agree. In this case the answer you're talking about answers the bit of info in the header, a problem statement which can be construed to be a question quite easily, without much of a stretch. It does indicate the person answering probably didn't read the entire question.
The original question can and should be modified such that the header agrees with the question in the body. The answerer probably could have made a comment with their partial answer.
This is not a rare case, but it is a case where one minor issue existed, and another minor issue was added as a result. The info in the answer is good, even if it isn't perfectly matched to the problem. Some coaching comments would help both improve their own parts of this, but overall, given that the partial answer IS a decent answer, even if it is only tangentially related to the issue, and it answers SOMETHING from the main post, I don't consider this particular case to be worth downvotes or close/delete votes.
