I can't figure out why I can't display my containers in my browser.

I want to run a jenkins image.
When I enter docker ps it returns me: 

> 
> a7adea029d28 jenkins/jenkins:lts "/sbin/tini -- /usr/…" 15
>  minutes ago Up 15 minutes 8080/tcp, 0.0.0.0:5000->5000/tcp,
>  50000/tcp test\_server
> 
> 
> 

If I enter `localhost:5000` it fails, if I enter `192.168.99.100:5000` it fails, the same if I try `8080` as port coordinates. 
I don't know what to do and can't figure out why it fails. 

I have tried on firefox also and it fails too,

if someone has any hint, would be great,
thanks
