It produced this output:

Welcome @PhatHT

Your DNS is not setup correctly. I do not have any specific suggestions for fixing it. But, you have two DNS servers listed but only "name0" replies with an IP address.

Let's Encrypt may use either one so both must reply with the correct IP.

hoadonmediaone.evat.vn. 3600    IN      A       103.252.1.230
