I have set up my bitcoin/lnd full node and found out that port 8333 is closed.
When checking using https://bitnodes.io it tells me it's down
I've checked the router config and port 8333 is forwarded to the IP of the node.
If I scan or use telnet to connect locally to my node, it seems to be blocked.
Also ufw has been checked and sudo ufw allow 8333/tcp has been added.
As well sudo netstat -tunlp tells me that the port is in listen state.
Now, I'm kind of stuck and looking for help.
Many thanks in advance for a reply and stay healthy.
