Can´t reach OH from browser

I´m trying to access OH from my browser via HostIP:8080 but it doesn’t answer.
When I try it on it´s work perfectly.
I´m already check my firewall and looks OK.

Anyone could help me.

If you are running Linux and you have netstat installed then on the console of your OpenHab machine you can run:

netstat -a --numeric-ports | grep LIST

or on Windows:

netstat -a | find "LIST"

Look in the output for a listening port on 8080. If it’s not there then you have a problem with OpenHab, if it is then it might be a firewall issue between your browser and your OpenHab machine.
