Custom domain verification not working even though DNS configuration is good
I want to use a custom domain api-preprod.funprono.com for my API.
I successfully added a CNAME entry with my registrar Infomaniak, but the verification keeps failing.
I saw a similar issue in this ticket: https://discord.com/channels/564160730845151244/1395340182810787840 So I added a CAA entry with certainly.com, but that didn't fix the problem.
The CNAME propagation is working, according to the DNS checker.
I don't know what to do anymore. Fortunately, this isn't my production environment, but I have to migrate my production environment to the cloud soon. I hope I don't have the same problem 😟
This is the request response for verification :
