title: Invoice Ninja with docker compose - Error 500
body: <p>I have setup Invoice ninja with docker-compose behind a nginx reverse proxy, which also manages the TLS certificate.</p>
  
  <p>As far as I can see from the logs, everything initializes correct, but when I navigate to the site, I can only see a 500 Server error.</p>
  
  <p>I provided my docker-compose and the logs until the first 500 error below.</p>
  
  <p>Thanks in advance!</p>
  
  <p><strong>docker-compose.yml</strong></p>
