Atlas stopped working

Good afternoon everyone,
I have this installation with Jeedom Atlas. It has stopped working. I have recovered with an image and the configuration has appeared again but it does not react.
When I try to update it gives me this error:
Erreur curl sur: https://market.jeedom.com/core/api/api.php. Detail: Resolving timed out after 15000 millisecoonds.
Any ideas?
Thank you

Hello

Seems that your box is not able to resolve name.
You have to check the DNS configuration.

In Jeedom configuration you are able to set this with one click
