Ok, I did a little searching and came across your earlier post: Serving .well-known/apple-app-site-association Works in Development env but returns Phoenix.HTML.Safe error in Release - #3 by maz
So I was able to add a directory:
/assets/static/.well-known/test.txt
/assets/static/.well-known/acme-challenge/test.txt
I’m still getting this error when running certbot:
[info] GET /.well-known/acme-challenge/_B_tSrUELGkILDnSgQJJxj6FHSVsW5zmiHx3T_dTGV4
[debug] ** (Phoenix.Router.NoRouteError) no route found for GET /.well-known/acme-challenge/_B_tSrUELGkILDnSgQJJxj6FHSVsW5zmiHx3T_dTGV4 (ExchatWeb.Router)
