Question Wordpress Website running PHP-FPM PHP 7.3 with Centos 7 shows 503 Service Temporarily Unavailable

[willbest]

My Wordpress Website running PHP-FPM PHP 7.3 with Centos 7 shows 503 Service Temporarily Unavailable: failed to make connection to WordPress frontend and backend. I guess it is a FPM issue as I have to access Services in Plesk and restart/refresh the 7.3 PHP-FPM before I can access the website again and in some few minutes as I try to load a page on the website it happens again. Again I heard back to restart the PHP-FPM.

Is there a way to solve this problem once and for all without the back and forth?

Please check the 503 message: https://i.postimg.cc/g0NjHr5J/503.png

IgorG, I am quite new to Plesk... Is /var/log/plesk-php73-fpm/error.log in the Files Manager or I have to use SSH to access it?

 

[IgorG]

I have to use SSH to access it

Yes, I assume you are investigating a problem using an ssh session.

I have logged into SSH how do I access the PHP-FPM Log?

I advise you to hire an experienced Linux administrator or contact Plesk technical support.
They will perform an investigation and fixing this problem directly on your server.
