Also, I have another node C. This node is on the same physical machine as node B. Note A and C can communicate together. Wondering if node A is getting confused between node B and C since they have the same IP address? Node C has port 9735 opened on the firewall.
Also, I have another node D. This is on the same physical machine as A. Node D can stay connected to node A.
Both node B and D have nolisten=true
set in lnd.conf
.
Hi @AndySchroder,
Could you please check the following just for some initial clarifications:
Does the connection remain up if you remove:
nolisten=true
On node B
?
Alternatively does the connection remain up if you keep the nolisten=true
on node B
, but never start Node C
?
I just upgraded from v0.16.4-beta.rc1 to lnd-v0.18.2. I believe that it worked fine on v0.16.4-beta.rc1
Since LND 18 we do enforce pong messages and will disconnect the peer if the don't get a reply in 30sec. Something seems not right with the connection.
Can you set the PEER subsystem to trace and provide the logs.
Background
peers don't stay connected
Your environment
lnd-v0.18.2
Expected behaviour
peers should stay connected and channels remain active.
Actual behaviour
I have two nodes on a local network, Node A and Node B. Node A has port 9735 open on the firewall. Node B has no open firewall ports. Restarting node B causes it to connect to Node A, but then after a few minutes, I get the following errors and channels go inactive. I just upgraded from v0.16.4-beta.rc1 to lnd-v0.18.2. I believe that it worked fine on v0.16.4-beta.rc1 .
