[Domain Mapping] Domain Mapping HTTP

Hello team,

I have a mapping problem on sites for our client VINCI ENERGIES.
Indeed, we have a \"private\" URL for the back-office that responds in HTTPS and for each site created a \"public\" URL which is either in HTTP or in HTTPS.

For sites in HTTP, the mapping returns to HTTPS from the BO. Do you have a problem?

Example :
- Not mapped : https://vinci-energies.beapi.space/socalec/fr/
- Mapped redirect to : https://www.socalec.fr/fr/
Or in admin setting in mapped domain, option is set to : http://www.socalec.fr

Thank you,
