Hi Charlotte,
Thank you for your answer !
I followed your recommendations and chose to stay with External DNS, I used the guides you sent me to set everything up correctly.
Everything seems to be working fine again. I managed to successfully renew the TLS certificate for my domain and the website is accessible.
I hope I followed the instructions correctly, could you check on your side if everything seems fine to you ? (As I made the modifications this morning, the changes to the DNS records may still be propagating until tomorrow)
I have one more question : I have a few other Netlify websites that were hosted on subdomains (ekko-gobelins.netlify.app for example, that I want to redirect to ekko.jordanthiervoz.com).
These subdomains are not accessible anymore as I removed every DNS record from Netlify and OVH in order to clean everything up.
When I try to re add my custom subdomain on the website’s Domain Management section, it says "Awaiting External DNS and asks me to use Netfly’s Domain Name Servers, which I don’t use anymore as I now use OVH Domain Name Servers correctly.
What do I have to do to make my subdomains available ? Do I only have to add a single DNS A record redirecting to Netlify’s IP address 75.2.60.5 for every subdomain or is there other steps to follow to make it work ?
