I am trying to configure a www domain on azure. I want to have website under this domain. My domain is "legia.fitness". I have created the DNS zone as follows:
On this picture you see 4 DNS servers. I have delegated my domain that I bought at home.pl to those servers:
And this doesn't work. When I try to browse legia.fitness I get "ERR_NAME_NOT_RESOLVED" error. What am I doing wrong?
Your Azure DNS zone does not have any A or CNAME records for www or @ so the name cannot be resolved to an IP address.
Add a new A record with the label @ set to the IP address of your Azure website, and another A record with the label www also set to the same IP address.
Alternatively, create CNAME records (both @ and www) and set them to your Azure Website's name (e.g. yourwebsite.azurewebsites.net). CNAME records are aliases of existing A or CNAME records, but are slower to resolve which is why I prefer A records.
You haven't directed the domain anywhere yet.
You have a DNS zone that works. I can see the SOA records on Dig web interface.
Now you have to add CNAME/A records to the DNS zone to direct the traffic to where you want it.
Here is a guide for Azure Web Apps: https://docs.microsoft.com/en-us/azure/app-service-web/web-sites-custom-domain-name
If you use something else, you'll need to find its guide.
