PageSpeed Insights received a 500 response from the server.

This fixed it for me with Server Pilot, your command may differ…

Restarted PHP-FPM services for all PHP versions on your server, which should fix the problem by SSHing in to your server as root and running this command:

service php7.0-fpm-sp restart

this problem appears to be from an Ubuntu security update that caused DNS resolution to begin failing for some running services, including PHP-FPM. This was the security update:

Thank you brother. How to solve my problem

I think this is SSL let’s encrypt problem. I’ve raised a support ticket with Server Pilot who auto install my certs. My updates failed today across all my sites and widget feeds aren’t working, it’s leading back to SSL. I disconnected my sites from MainWP and manually updated the non-SSL sites with no problem, but SSL sites are having RSS feed issues, updates aren’t working with this response: Download failed. cURL error 6: Could not resolve host:

Stuck until SP respond…

Hi @Abdo

First things first: Do NOT create multiple threads about the same issue. It will just make it much more difficult to answer.

Second: This is a community forum (meaning user-to-user), so treat it like that.

It sounds like you need to hire a server administrator to fix the problems.

You need to look in your web server log, which is probably Apache or Nginx, to find the reason for the 500-error.
