Hej,
Ktoś ma pomysł co się może tutaj dziać:

$ rake routes RAILS_ENV=production
              acme_plugin       /                                                                                        AcmePlugin::Engine
Routes for AcmePlugin::Engine:
       GET  /.well-known/acme-challenge/:challenge(.:format) acme_plugin/application#index

cat log/production.log

Cofnąłem z rails 5.2.3 i ruby 2.6.1 do rails 5.2.0 i ruby 2.5.1 i to rozwiązało problem.
Edit: a wystarczy cofnąć samo rails
