Support of multiple domains

[edzob]

Dear all, I hope you all can help me in determening if this is my configuration error or a possible feature/bug. Mostly it is the first :)

docsy and multiple domains
For a project site I use gitlab + hugo + docsy theme.
The baseurl in the config is:
baseURL = "https://www.pronto-lectures.org"
This site can be viewed on five domains:
https://edzob.gitlab.io/pronto-lectures ;
https://www.pronto-lectures.org ;
https://pronto-lectures.org ;
https://pronto-lectures.com ;
https://www.pronto-lectures.com

In this case only the .org domains work in page render and favicon.

beautifulHugo and multiple domains
For my personal site I use gitlab + hugo + beatifulHugo theme.
The baseurl in the config is:
baseurl = "https://www.edzob.com"
This site can be viewed on three domains:
https://edzob.gitlab.io/ ;
https://edzob.com/ ;
https://www.edzob.com/

This site works in the page render and favicon.

Gitlab Pages
My assumption is that gilab pages works the same as Github pages but to be complete. For gitlab pages you write a redirect in DNS from the "alternative" domains toward the gitlab (pages) subdomain.
Since my personal site works with this method my assumption is that this is not part of the root-cause.

My question
Is there a way I can edit the config.toml to render on all 5 domains of my project website with docsy?

thanks for your help and advice.

Solved by itself in time.
