News app stop fetching new news from RSS

Hello. I recently realize that, my news app stop fetching new news.

I’m using nextcloud 12.0.4 and news app is version 11.0.5.

I’m running the cron.php through system cron
crontab -u www-data -e

*/15  *  *  *  * php -f /var/www/nextcloud/cron.php

and no error exist at Admin->Logging page.

Also I execute the cron.php from the SSH like sudo -u www-data php -f cron.php and without any problem (nothing is printed out)

Any idea / hint on what might be happening ?

What else should I check ?
