I have been online for about 11 hours, but HUG nodes is showing OFFLINE

Which is your node?
If you want to support the HUG network, you must allow inbound connections. Computers connected directly to the Internet usually dont require any special configuration. Home connections are usually filtered by a router or modem. HUG wallet will request your router automatically configure itself to allow inbound connections to port 11111. Unfortunately many routers dont allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 11111. Another way if you add "addnode=hugcoin.online" line to hug.conf file and restart the wallet because this start the outbound connections.
In the future if someone answered the support questions of others then i will automatically send 200HUG to helper.
go to debug window ---- > Consol
Type this : addnode hugcoin.online onetry
You can check your node : getpeerinfo
Resolved. It's ONLINE now. Thanks dev!
