Problem with my SSL certificate

[tgxworld (Alan Tan)]

Is your domain’s IPv6 address configured correctly? We had a similar issue previously

Not able to access site after letsencrypt cert expiry and rebuild due to IPV6

I worked with @Umashankar_Ankuri and this looks like a case where the domain’s IPv6 address was configured incorrectly causing the validation check to fail. https://github.com/Neilpang/acme.sh/issues/867 @Umashankar_Ankuri can confirm the problem once he fixes his DNS settings.
