Use domain name

Hello, I am trying to use my domain name votre-coach-personnel.com but when opening with https://votre-coach-personnel.com" I get an error message:
votre-coach-personnel.com utilise un certificat de sécurité invalide. Le certificat n’est valide que pour les noms suivants : *.000webhostapp.com, 000webhostapp.com Code d’erreur : SSL_ERROR_BAD_CERT_DOMAIN”
Translation:
" votre-coach-personnel.com uses an invalide security certificate. The certificate is valid only for *.000webhostapp.com, 000webhostapp.com. Error code: SSL_ERROR_BAD_CERT_DOMAIN"
Could you please advise on how to correct for this? Thanks in advance.

Hi, to fix this you should setup your domain name using this tutorial.

Thanks for the reply. I have moved a little forward. I followed instructions for cloudflare and changed DNS to those of cloudflare. On Cloudflare the site is said to be active. When I open the site with https://www.votre-coach-personnel.com on my computer I get the green lock and the site opens normally. When I try opening it from another computer the lock is red and https crosschecked. From an iPad it is just not possible to open and a message indicates that the site is not available. Any clues to this?

It’s showing the green padlock on my device.

Thank you. Great. On the iPad it is now ok. My husband’s computer still displays the grey lock with the red cross and I can’t figure why on his computer only.

can you just try Hard Refresh in browser (ctrl + shift + r) or just clean cache files. hope this will work!

Neither ctlr+shift+r nor cleaning cache files did do it for an unknown reason. It works for other on iphone, iPad and computers. Unless some of you have other advice I think I will leave it for now.
