The site is accessible by ip but not by domain, what should I do?

Question

Domain Name System

The site is developed on Rails and deployed on DigitalOcean, hosting is registered on freenom.com.
I made the settings for addressing as it should,
but nothing happens by the name of the site, what is it and how to fix it, help me figure it out.

Answer 1

You need to hit the DNS provider because your domain is being resolved through a completely different registrar. And let them figure it out. As a last resort, you can sue for the inadequate quality of the services provided - but read the contract. According to the data available in the DNS response, your registrar does not have rights to the teacher-office.cf. domain, and, as a result, does not have the right to sell it to you.

Answer 2

$ dig +trace www.teacher-office.cf
...
www.teacher-office.cf.	0	IN	CNAME	teacher-office.cf.
teacher-office.cf.	300	IN	A	195.20.53.45
cf.			10800	IN	NS	a.ns.cf.
cf.			10800	IN	NS	b.ns.cf.
cf.			10800	IN	NS	c.ns.cf.
cf.			10800	IN	NS	d.ns.cf.

Answer 3

you can sue for inadequate quality of services provided

Are you trolling or are you actually advising to sue digitalocean or freenom? Neighing...
