I stopped trusting this application when I realized my some of my self hosted services were exposed without authentication, despite the configuration being set. Apparently there had been an bug open for months that authentication didn't work.
I accept it's my fault for not re-testing this often, but what a huge issue. It's vanilla Nginx or Caddy from here on out, it's not worth introducing a third-party security risk.
Mine just stops renewing certificates so I stopped fighting it. Haven't replaced it with vanilla Nginx yet but that's a project on my todo list.
You can try nginx-proxy, its similar to trafeik but based in nginx and a bit easier.
