recurrent 503 error problem

[mourad13]

Hello,

I have a 503 error problem on my website.
Here is the configuration of the infra:
The Pfsense in firewall with ACME and HAproxy.
In a VLAN, the web server (Apache 2.4 and PHP7.3)
In another VLAN, the database (MariaDB).

The site works fine most of the time. However, once or twice a week (The last date today, and another time Tuesday), I have this error 503 displayed :

Everything works again when I restart the Pfsense machine.
Additionally, during the outage, Apache, PHP, and MariaDB seem to work fine.

Anyone already had this problem or know how to analyze / solve it?

Thank you.

Hi. I have a similar problem with the site. Contacted programmers, they can do nothing. Most likely these are technical problems with the server.

Today, everything works smoothly. The reason remained unclear.
