PHP passthru execution system command times out?

<code>        passthru('cd ' . config("log")["analyse_dir"] . ' &amp;&amp;  ' . config("log")["python"] .' '. config("log")["analyse_file"] . ' &gt;&gt; ' . config("log")["analyse_log"], $ret);
        if ($ret == 0) {
</code>

This is echoed in brackets.

cd /MyApp/water/water && /usr/bin/python start_analyse.py >> /MyApp/shy/public/../storage/logs/analyse.log

Then the 504 timeout error is always reported after the api call.
This command is a database analysis and storage operation. Although http reports a 504 error, the log can still be entered and successfully entered into the database.
That is to say, the command was executed successfully.

How to solve this timeout error?
