Production site intermittently going offline

[stevelewis33]

I'm hoping someone will be willing to help me, we are using symfony/docker in production for our company web site and are having intermittent issues that I'm really struggling to debug, the whole site stops responding, the browser states "The connection to ... is not secure".

The logs from Docker around the time of the incidents don't reveal anything obvious, our monitoring tool reported the site was offline at 00:41:44 (UTC) this morning and it remains offline until I re-run our deployment script. The Docker frankenphp service seems to continue to receive and deal with requests but the responses don't seem to reach the users browsers.

Do you have any suggestions for additional debugging I could try?

What other information can I provide here to help you help me debug it?

Hi, @stevelewis33!

From the description, what comes to mind is the lack of IP routes to the Internet (to the user’s browser).

Do you have the ability to check whether the response from another web server (for example whoami) from the same host will reach the user's browser?
