Feed not found - Can’t add a feed because no feed was found. #2055

Closed kiwijuice closed 2 years ago

kiwijuice commented 4 years ago

The following feed can not be added to NetNewsWire. However it can be added to other RSS services (i.e flowreader):

When I'm trying to add it, I get the following message: Feed not found - Can’t add a feed because no feed was found.

These feeds are valid, according to the w3 validator: https://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fwww.gov.il%2Fhe%2Fapi%2FNewsApi%2Frss%2Fd6b46ce2-975b-43ee-afbd-404ba29b01e8

When I try to download these via the command line, I get a 404 Not Found error on each. We don’t plan to deal with this.

Is there any way to enable logs, I'll check it?

I think this server doesn't support HEAD requests, maybe that's the problem?

brentsimmons commented 4 years ago

Ah! I see.

My guess is that the issue is that it’s using UTF-16 encoding, and our feed-finding code may not work with UTF-16. So I’ll reopen this.

I've encountered another UTF-16 feed: https://blog.briancmoses.com/atom.xml

brentsimmons commented 3 years ago

The feed claims that it’s in UTF-8 encoding…

<?xml version="1.0" encoding="utf-8"?>

…but you’re correct, it’s UTF-16.

This comes up so immensely rarely that it may be a long time before we deal with it.

Here's another feed example that seems to be drumming up the same "Feed not found" error message: https://www.mcknightsseniorliving.com/feed/

And the results from curl:

When I use curl to view the response body — the actual feed — I get nothing. Zero bytes. It’s worth reporting a bug to the feed owner.
