Explain the Problem

When I add some feeds I get an Internal Server Error. This happens only with some feeds, not all.

Steps to Reproduce

Explain what you did to encounter the issue

Click Subscribe
Paste feed URL (example: https://alepiumetti.github.io/feed.xml) and click Subscribe (tried both with and without auto discover feeds)
A popup appears with the message "Internal server error! Please check your data/nextcloud.log file for additional information!"

I've also been getting errors lately, namely these two:

https://www.criticalmass.at/category/wien/feed/ read error : cURL error 60:
SSL certificate problem: unable to get local issuer certificate

and for https://blog.joaograssi.com/rss:

An exception occurred while executing a query: SQLSTATE[HY000]: General error:
1364 Field 'title' doesn't have a default value

The first site seems to somehow have configured their SSL wrong, I don't know what's wrong with the second one though. It seems to be a standard feed generated by Hugo, and there's a title for the whole feed AND for every single post as far as I can tell.

News App: 24.0.0 Nextcloud: 27.1.5

Similar issue: I'm trying to subscribe to Nextcloud's activity app's RSS feed and end up with an Internal error. Logs yield:

RequestException cURL error 60: SSL certificate problem: unable to get local issuer certificate

I'm pretty sure my SSL conf is solid, I have a Let's Encrypt certificate and browsers have no problem connecting to my Nextcloud instance. The only problem I can foresee is my cert being pretty recent, so solving this issue might just boil down to updating cURL's root CAs ?

That means your server doesn't know how to verify the certificate that your server is presenting. You'll probably get the same if you curl the url from your server.

That means your server doesn't know how to verify the certificate that your server is presenting. You'll probably get the same if you curl the url from your server.

Thanks for the hint ! Turns out I was actually supplying my apache conf with the standalone cert instead of the full chain.

It's interesting how some softwares (such as firefox) are fine with this, while others (like cURL) are not.

Apr 23 '24 05:04 Holbormon

As a rule browsers will forgive almost anything since web developers all seem to follow a different standard. cURL will hold you to the standards though.

Apr 23 '24 05:04 SMillerDev

Mozilla also provides it's own trust store for Firefox so it's not necessarily in sync with the OS.
