Lets encrypt issue google cloud vm instance

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

Your DNSSEC is broken: https://dnsviz.net/d/krizovany.online/dnssec/

While DNSSEC isn't mandatory when requesting a LE cert, when it does exist somewhere, it needs to function properly.

I don't know how it broke, nor how to fix it, but DNS is broken - even Google DNS can't resolve it:

nslookup krizovany.online ns-cloud-c1.googledomains.com
Name:    krizovany.online
Address:  34.82.83.181

nslookup krizovany.online 8.8.8.8
*** dns.google can't find krizovany.online: Server failed

-i think i have requested dnssec key on my domain registrar by mistake...i have deleted it now, so i will see if its help
-on server DNSsEC is off
