I have set up a private geth network with a bootnode and a single signer node. I start the bootnode first then the signer node. The signer node starts mining (using PoA) but in the bootnode logs it says
Revalidated node then
Removed dead node.
This happens if I decided to add another node to the network. I have not been able to have nodes connect to one another and I'm wondering if the bootnode is pruning. (for some reason) the nodes that are trying to connect.
