Problem with DNS name resolution in iPhone's Capsule Connect app.

[PauloProdabel]

Hi, everyone. I'm facing a situation using Capsule Connect App in iPhone. When I connect to the VPN server, I cannot access web sites that are located inside the network (only those that doesn't have a public IP address). The error I get from the browser is "ERR_NAME_NOT_RESOLVED".

When I try to access URL with its private IP address, I got success with the connection.

Another test I did was adding private network DNS server when I log into VPN server, and the resolution name was done successfully.

This problem doesn't occur with smartphones running Android.

Has anyone already faced that?

Can someone help me?

Thanks in advance.

Does the device have an IPv6 address?

Have you already looked at articles with these symptoms such as: 

sk180004, sk137676, sk103772

Thank you, Chris_Atkinson. sk103772 saved my day.

The problem was that we have already had 3 suffixes. It was missing the fourth one, and we haven't realized it.

Once again, thank you very much for your answer.
