Change the path url in a mail with Docker installation

[ZerooCool]

I have installed DemocracyOS with docker : http://unis-pour-la-planete.com:3000/

French tutorial upgrade : https://www.visionduweb.eu/wiki/index.php?title=Installer_DemocracyOS#Installer_DemocracyOS_avec_Docker

I need change the path url, in the mail.
I have this in the mail : http://mongo:3000/signup/validate/5bb6a423.....

I can not click to validate it.
I get around this problem by sending back the message, and, changing mongo:3000 by my http://mydomain.tld

Can you test my installation (copy paste from my tutorial) and give your opinion, to change the path of the email validation?

Can you give help for fix that ?
