I used the above command and it gave me the above error. My domain was resolving to this IP previously, but now it has been changed to 35.154.107.12. What can I do to install the https certificate?
PS: I was able to install SSL certificate for my 2 other domains on the same host, but getting problem with this domain.
It looks like you forgot to change the DNS record for www.thekosmix.com, which is a different record from thekosmix.com. thekosmix.com points at 35.154.107.12, but www.thekosmix.com points at 52.77.98.146. If you change both, it should work for you.
