Our server use hostname called host3.domain.net and we add this as virtual server in Virtualmin. However we have issue enabling SSL certificate for this subdomain with error as below:
Validating configuration for host3.domain.net…
… errors were found, which will prevent Let’s Encrypt from issuing a certificate :
Apache website : An IPv6 DNS record host3.domain.net with address ::1 exists, but this virtual server does not have IPv6 enabled
We don’t run any IPV6 in the web server and make sure no IPV6 advertised for host3.domain.net in our DNS.
Thank you IIia for the prompt response. Yes we are aware about the skip tests option and it works really well when we renew certificate manually. However when we back to the SSL certificate setting again, the option back to Validate domain instead.
Aside of that we make sure that there is no ipv6 advertised in our DNS for this hostname. I tried again this morning using updated 6.15 Pro version and now getting another ipv6 address instead ::1 :
