This is a brief list of common issues that come up with NextCloud News.

My browser shows a mixed content warning (Connection is Not Secure)

If you are serving your Nextcloud over HTTPS your browser will very likely warn you with a yellow warnings sign about your connection not being secure.

  • Chrome will show no green HTTPS lock sign.
  • Firefox will show you the following image Mixed Passive Content Mixed Content Type

Note that this warning is not red and won't block the page like the following images which signal a serious issue:

  • Chrome Chrome error
  • Firefox Firefox error

What is the cause of the (yellow) error message?

This warning is caused by mixed passive content and means that your page loads passive resources from non HTTPS resources, such as:

  • Images
  • Video/Audio
  • Some Ads

This allows a possible attacker to perform a MITM (man-in-the-middle) attack by serving you different images or audio/video.

Why doesn't the News app fix it?

The News app fully prevents mixed active content by only allowing HTTPS iframes from known locations; other possible mixed active content elements such as <script\> are stripped from the feed. Because images and audio/video are an integral part of a feed, we can not simply strip them.

Since an attacker can not execute code in contrast to mixed active content, but only replace images/audio/video in your feed reader, this is not considered to be a security issue. If, for whatever reason (e.g. feed which would allow fishing), this is a security problem for you, contact the specific feed provider and ask him to serve his feed content over HTTPS.

Why don't you simply use an HTTPS image/audio/video proxy?

For the same reason that we can't fix non HTTPS websites: It does not fix the underlying issue, but only silences it. If you are using an image HTTPS proxy, an attacker can simply attack your image proxy since the proxy fetches insecure content. Even worse: if your image proxy serves these images from the same domain as your Nextcloud installation, you are vulnerable to XSS via SVG images. In addition, people feel safe when essentially they are not.

Since most people don't understand mixed content and don't have two domains and a standalone server for the image proxy, it is very likely they will choose to host it under the same domain.

Because we care about our users' security and don't want to hide security warnings, we won't fix (aka silence) this issue.

The only fix for this issue is that feed providers serve their content over HTTPS.

I am getting: Exception: Some\Class does not exist errors in my nextcloud.log

This is very often caused by missing or old files, e.g. by failing to upload all the News app files or errors during installation. Before you report a bug, please recheck if all files from the archive are in place and accessible.

Feeds not updated

Feeds can be updated using Nextcloud's system cron or an external updater via the API. The feed update is not run in Webcron and AJAX cron mode!

Validating Using System Cron


This requires Nextcloud 26 or newer and News 24.0.0 or newer.

Follow this checklist:

  • Check admin settings of Nextcloud, was the last cron execution ok.
  • Check the logs for errors.
  • Does your cache configuration work?
  • Check the News admin settings, system cron is used to update news.
  • You should see a info card at the top, which will tell you when the last job execution was.
  • If the card is red it is very likely that the update job is stuck.
  • If it is green then maybe only some feeds are failing to update, check the Nextcloud logs.

If you believe the job is stuck you can reset it. For further steps you need to use occ.

You can check again the status of the job. (replace www-data with your httpd user)

sudo -u www-data php ./occ news:updater:job
Checking update Status
Last Execution was 2023-03-20 12:20:03 UTC

The same check that is done in the News admin settings can be done using occ too. Adding the --check-elapsed option displays the time elapsed since the last execution, and if it's considered too long ago, a message will be displayed, and the command returns with exit code 2. This can be used in scripts to send an alert for example.

$ sudo -u www-data php ./occ news:updater:job --check-elapsed
Checking update Status
Last Execution was 2023-03-20 12:20:03 UTC
8 hours, 21 minutes, 20 seconds ago
Something is wrong with the news cronjob, execution delay exceeded the configured interval.

If you think the job is stuck you can reset it, this may lead to issues if the job is currently running!

sudo -u www-data php ./occ news:updater:job --reset
Checking update Status
Last Execution was 2023-03-20 12:20:03 UTC
Attempting to reset the job.
Done, job should execute on next schedule.

The output of the command should have changed.

sudo -u www-data php ./occ news:updater:job
Checking update Status
Last Execution was 1970-01-01 00:00:00 UTC

After some time has passed the timestamp should be close to the current time.

If this did not help, check the logs and open a issue or discussion on GitHub.

Outdated Steps

Follow these steps if you are running an older version of News and Nextcloud.

  • Check if you are using the system cron (Cron) setting on the admin page. AJAX and Web cron will not update feeds
  • Check if the cronjob exists with crontab -u www-data -e (replace www-data with your httpd user)
  • Check the file permissions of the cron.php file and if www-data (or whatever your httpd user is called like) can read and execute that script
  • Check if you can execute the cron with sudo -u www-data php -f nextcloud/cron.php (replace www-data with your httpd user)
  • Check your data/nextcloud.log for errors
  • Check if the cronjob is ever executed by placing an error_log('updating'); in the background job file. If the cronjob runs, there should be an updating log statement in your httpd log.
  • If there is no updating statement in your logs check if your cronjob is executed by executing a different script
  • Check if the oc_jobs table has a reserved_at entry with a value other than 0. If it does for whatever reason, set it to 0. You can check this by executing:
SELECT * from oc_jobs WHERE class LIKE '%News%' ORDER BY id;

You will get two rows where column class will be OCA\News\Cron\Updater and OCA\News\Cron\UpdaterJob.


In newer versions of News (21.x.x) the old job OCA\News\Cron\Updater was removed from the DB.

Reset the reserved_at by executing

UPDATE oc_jobs SET reserved_at = 0 WHERE id = <id from above SELECT statement>;

If your cron works fine, but Nextcloud's cronjobs are never executed, file a bug in server

Using External Updater

  • Check if your configuration is set to not use the system cron.
  • Consult the documentation of the updater
  • Check your data/nextcloud.log for errors

Database table grows too big

If your users have subscribed to some high-volume feeds where a lot of items remain unread, this can lead to an oversized news table over time. As a consequence, the database upgrade of the news app can take several hours, during which Nextcloud cannot be used.

By default, Nextcloud News purges old news items above a certain threshold each time it fetches new news items. The maximum number of items per feed that should be kept during the purging can be defined through the “Maximum read count per feed” setting in the admin UI or the autoPurgeCount value in the config. Additionally you may enable the option to also purge unread items purgeUnread. This is useful if your users have large amounts of unread items. Starred items are always exempt from purging.

The command occ news:updater:after-update [--purge-unread] [<purge-count>] can be used to manually purge old news items across the instance. With the --purge-unread option, unread items are also purged (starred items are still exempt). If purge-count is not specified, the configured autoPurgeCount is used.

The purge count only applies to the items that are purged. For example, when purging a feed that has 100 unread items, 100 starred read items and 100 unstarred read items, using a purge-count of 50 would keep all unread and starred items and the latest 50 read items. Using a purge-count of 50 along with --purge-unread would keep the all starred items plus the latest 50 from the set of unread and read items.

Missing 4-byte support SQLSTATE[22007]: Invalid datetime format: 1366 Incorrect string value:

This is likely caused by your feed using emojis in the feed title or text.

The DB is then not able to store the feed and runs into strange decoding errors.

You need to convert your DB to support 4 bytes, check the Nextcloud documentation.
