On the tutorial it says to make the A record name ‘@’, but my hosting provider shows that a zone name must be domain name. Is it the same thing? So in other words an A record Name should be myDomain.com. and not @. Can anyone verify?
I just spend several hours last weekend to find an answer to that question for myself
So YES, myDomain.com. is correct.
And for the CNAME record do not forget the dot at the end of proxy-ssl.weblfow.com. like I did
Yes. Every DNS host handles things differently. Some require nothing, some require @, some require the whole domain.
As @johanneskain mentioned some providers also require a trailing dot at the end of records.
