I had a problem. I needed to change domain name of the server – aka nameserver. It was already using some other name so the problem is there. After changing nameserver it didn’t work. It was redirecting me back to the old nameserver.

2. You need to update let’s encrypt with the new nameserver ( https://help.directadmin.com/item.php?id=629 )
3. https://www.directadmin.com/features.php?id=801
4. Mass update dns for all domains – https://help.directadmin.com/item.php?id=141

That’s it.
