Unable to redirect www to non www

[seanpaulharsevoort]

Dokku: 0.35.5
Dokku-redirect: 0.9.1

I want to redirect www traffic to non www.

I also followed this tutorial

Steps i took:

1. used the redirect command: dokku redirect:set myappname.com www.myappname.com myappname.com 301

According to chatgpt i had to create a redirect app:
2. create redirect app: dokku apps:create redirect-www
3. set the domain: dokku domains:set redirect-www www.aha-adviseurs.nl aha-adviseurs.nl
4. run letsencrypt again.

Also the domain registry has a www CNAME record that points to the domain.

Unfortunate part is, that all of these steps are not working. I also undo every step and used the chatgpt one, without any luck whatsoever.

If anyone could help me that woulde be awesome!
