Those are all inbound services. You don’t want your firewall restricting outbound connections. 

Have open port 80 and 443 for all IP traffic but as you can see, it's still too little to work.

Add more infromation. Board working but can't reflash license and see this error. 
Why I use this firewall and can't disable, because I have for my IP open FTP, SSH port.

Thanks for any reply.

Hi i use on my hosting (OVH) firewall on panel OVH.
I block all ports TCP and UDP. Only have open 80 and 443 and have problem to checking license and connection:

Connections to external sites are not working properly. This can cause problems with unofficial services. Contact your hosting (server) provider and ask them to resolve this issue.
