Hi,
I have a node that passed the reachability check before. But today, after stopping and restarting the node, it failed to pass the check.
What does this mean, and do you have any suggestions on how to investigate the issue?
My node is running on Ubuntu, UFW is disabled, and the config.yml is properly set up to use ports: 8336, 8337, and 8338.
Thank you.
Are you running your node at home? If so, you want to set up port forwarding on your router or similar.

I tried using the command:
tcpdump -i any udp port 8336 -c 20
and below is the result:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on any, link-type LINUX_SLL (Linux cooked v1), capture size 262144 bytes

Yes, I am running my node at home. I will check the link you provided.
