5. What I already tried:
Made a symfony project, created test.html and test.php (with phpinfo()).
Tried refreshing all files in Chrome, only php files are giving http error 500 randomly.
also tried with curl and here the php files also randomly gives http error 500.
curl -v --http2 https://poul.dev/test.php
