Mattermost works with the curl command, but not in a browser

Summary

juste after the installation, when I check the installation with the curl command like the documentation say, it’s OK, but after, when I try to connect the Browser of my computer, it don’t work.

Steps to reproduce

CentOS 7
Posgresql 9.4
Last mattermost version

Expected behavior

response of : curl http://localhost:8065

etc...

It’s OK, it was a bad configuration on the Linux firewall. I have configure the linux firewall with :
firewall-cmd --zone= --add-port=8065/tcp --permanent
firewall-cmd --reload
