I saw a lot of logs there like this in OpenWRT system log from edge daemon: and the p2p network is unreachable, I am wondering if this is related to the recent broadcast limitation change, what is that change did and impact at all? can you guys give a hint? thanks

recent broadcast limitation change

What exact change are you referring to?

can you guys give a hint?

Just guessing here and in case it actually is broadcast-related (which I do not know), does your system have a default gateway configured?

I mean change #958

Logan007 commented 2 years ago

958 is for making sure that broadcasts inside the virtual network only get forwarded to active federated supernodes (not the inactive ones anymore).

The sendto error message from your log indicates some issue with the underlying real network.

So my first guess here would be that it is not related. But maybe we can hear more opinions on this?

Checked. Configuration problem, thanks!
