Error code 422 with validated OpenWrt feed

[Dennethan]

Hi,

I get a code 422 error when I tried to subscribe to the next OpenWRT RSS link:
https://forum.openwrt.org/c/announcements/14.rss

It looks that the feed is valid:
https://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fforum.openwrt.org%2Fc%2Fannouncements%2F14.rss

In the log I can find the the next related entries:

[news] Warning: https://forum.openwrt.org/c/announcements/14.rss read error : internal server error
	POST /apps/news/feeds
	from <ip> by <user> at Apr 20, 2026, 4:16:07 PM

Can you post the full log output (redactions are fine)

I checked the feed and it seems news is blocked by the openwrt server, at least on my site.

The error is not handled properly, but catching 429 in lib/Fetcher/Client/FeedIoClient.php shows the correct fetch error:

Client error: `GET https://forum.openwrt.org/c/announcements/14.rss` resulted in a `429 Too Many Requests` response:
Too many crawling requests. Error code: nextcloud-news_crawler_rate_limit.

Yes it looks the case:

curl -A "NextCloud-News/1.0" https://forum.openwrt.org/c/announcements/14.rss
Too many crawling requests. Error code: nextcloud-news_crawler_rate_limit.%  

With another random user agent I manage to get the feed.

For what I see this is a know issue #2049, with @SMillerDev not so friendly with the idea of starting an user agent war. 😄

I will try to ask in Openwrt's Discourse forum.

Thanks

Maybe they blocked because of some users that use this feed have the full-text feature (web scraping) active, which causes extensive requests. This is fixed in 28.2.0 (#3631).
So you can also ask the Openwrt admins if they can whitelist at least news 28.2.0 and above.

OpenWRT has just whitelisted Nextcloud news.

Thanks to all.
