Can't subscribe to some feeds that look fine when requested manually

[bekopharm]

Some feeds never show any entries despite having a successful subscription. I suspect it's date related.

Yarns Microsub Server Version 1.0.2
WordPress Version 5.2.3

Some render a preview on adding:

https://hroarr.com/feed/

This may actually be due to age of posts. Description says Number of days to store feed items before deleting so one assumes it's number since fetched and not since today.

Some not even that:

https://medium.com/feed/okuna

When executed manually via wp-cli only plenty of warnings about Date show but script succeeds:

wp-cli.phar --debug cron event run yarns_microsub_server_cron
[...]
PHP Warning:  A non-numeric value encountered in wp-includes/SimplePie/Parse/Date.php on line 694

Thanks! Actually age of posts is referring to the number of days since the post was originally published. This fit my use case of treating Yarns as a newsfeed, but I can understand your interpretation. I should rephrase that text in the interface. I’ll check out the other example when I get a chance. (Been on a roll at work and not had much downtime but hopefully I will soon)

Looking into the Medium feed.

I'm not seeing the warnings about Date, but that may simply be because I've updated the Parse-This library on my testing server and the problem has been solved there.

However, I'm also not getting any results. When I try to preview https://medium.com/feed/okuna the following is returned:

{"url":"https:\/\/medium.com\/feed\/okuna",
"name":"<![CDATA[Okuna - Medium]]>",
"_raw":{"meta":{"title":"<![CDATA[Okuna - Medium]]>"}},
"_parse_time":0,
"_post_limit":5}

I noticed an oddity that might be responsible:
When I access https://medium.com/feed/okuna in my browser, the content-type header is text/xml

When I ran the script through Parse_This_Discovery->fetch(), the content-type header is returned as text/html. If Parse-This doesn't recognize the feed type, it won't be able to parse it correctly, leading to 0 items in the feed.

@dshanske - Do you have any thoughts on this?

Maybe cloudflare. When I try to reproduce this with curl (Accept: text/html) I still get content-type: text/xml; charset=UTF-8 returned. XML looks legit too.

With the medium feed, I'm getting Service Unavailable. Suggests it doesn't like my user agent.
