I run custom-api with fastAPI and using DO droplet ubuntu server. canyoutest.me is a testing domain and all the DNS A records are created and pingable.

Some ideas/advice on what's wrong with my configuration?

Hello @igormicev,

I tried to reproduce your issue, but I am missing your python app to make it work.

Can you provide the full DEBUG traefik logs of the latest traefik version ?
