Workers app don't resolve to IPV4 only request

Website, Application, Performance DNS & Network
1

What is the name of the domain?

teambrazil.app

What is the error number?

IPV4 request don’t resolve

What is the error message?

IPV4 request don’t resolve

What is the issue you’re encountering

IPV4 request don’t resolve

What steps have you taken to resolve the issue?

Hi, I have a new deployed app in workers but it does not resolve to IPV4. Only IPV6
curl -4 https://www.teambrazil.app/auth/login (this does NOT work)
curl -6 https://www.teambrazil.app/auth/login (this works)

The problem is that some customers don’t have IPV6 configured on the wifi router and this blocks the access to the app.

What feature, service or problem is this related to?

DNS records

What are the steps to reproduce the issue?

curl -4 https://www.teambrazil.app/auth/login (this does NOT work)

It’s resolving ok for me and in all these places…

Try another DNS resolver and see if that works for you.

DNS seems to be OK, but I cannot access the app in IPV4 ONLY
curl -4 https://www.teambrazil.app/auth/login

That seems to be the problem.

4

I have another app in workers that is exactly the same but it works
curl -4 http://api.bepersonal.com.br

I think there is some networking problem with www.teambrazil.app because I can ping api.bepersonal.com.br but I cannot ping www.teambrazil.app

5

It’s still working ok for me. Try another DNS resolver.

You are correct, using another resolver solved
