Why my new server shows numbers in the URL address

Question

I had to create a new AWS Server because the current server will be disabled, and I'm having some trouble about the domain/subdomain.

The current server has this domain: http://agile.tecomat.com.br

I already created a new server and inserted a subdomain, called: http://teste.tecomat.com.br

But, in the URL address, the current server shows this: 

And the new server, shows this in the URL address: 

What do I need to do so that the new server be like the current one in the URL address?

Edit: By the way, another problem that I'm having is that my DNS only works if I insert the port 3000. Like: http://54.89.39.213:3000 If I tried to open the website only with http://54.89.39.213, it doesn't work, anyone knows why is that? And what I have to do to "fix" that?
