I've recently purchased VPS hosting and followed the FAQ on "How do I set up a domain using Dynadot's VPS with Sentora".
In Sentora I've added the domain, which says is 'Live'. Created nameservers in the DNS manager. The A tab were IPv4 addresses, the NS tab gives ns1 & ns2 and the domain (bootshuis.be).
In my Dynadot account I've also added the nameservers and linked my domain to the nameservers. In the domain manager I can see the right nameservers.
However the site itself gives the Not Found error. I've waited a couple of hours for the changes to take place but nothing happens.
Unfortunately as VPS hosting is an unmanaged service through Dynadot, we aren't able to assist with troubleshooting or set up. We do offer some FAQs on common issues, which can be found by typing VPS in the search bar here: https://www.dynadot.com/community/help/.
We apologize that we could not be of any further assistance.
