This morning many people, including Laravel News, are experiencing that their sites are erroring when communicating with third party systems. The hostnames couldn’t be resolved and causing all those to fail.
The apparent fix is to restart either PHP-FPM, Apache, or Nginx. If you are using Forge you can SSH in and run:
1sudo service php7.0-fpm restart
Replacing “7.0” with your installed PHP version, or restart the Nginx service from the Forge admin.
I haven’t been able to pinpoint the actual cause but on social media, some are saying it’s related to an Ubuntu nightly security update.
In my tests it was just web requests, anything ran through the CLI would still work fine, but that meant that my Bugsnag errors couldn’t be logged, and all the API calls failed.
Update Mar 22, 2017: In today’s Ubuntu Security Notice USN-3239-2 they have reverted the change that caused issues yesterday. That means that long-running services that were restarted to compensate for USN-3239-1 update will need to be restarted again.
