SSL installation error: dns for domain does not exist, while it does.
How to install ssl cert.?
Your dns server is not working fine:
If we try to trace your dns resolution we get an error:
$ dig netmack.com ns +trace +nodnss -4

If we check whether net servers have your ns and glue records, it shows the right ones and that is good:
$ dig @a.gtld-servers.net netmack.com ns
; <<>> DiG 9.18.19-1~deb12u1-Debian <<>> @a.gtld-servers.net netmack.com ns

But if we try to ask directly to your server, we receive a servfail so your dns server is not working fine.
