Operating system: Debian 10
I guess I have a problem with DNS, related to OVH fire. I have 2 NS, with slave master on a VPS with OVH (now is offline)
Is this a problem to renew a certificate? (now I have only 1 namespace working)
I get this from Let’s Encrypt:
" DNS-based validation failed : Only the offical Let’s Encrypt client supports DNS-based validation"
