Nodes do not reconnect automatically after connection to signaling server is lost

After disconnecting from wifi and connecting again on my laptop, it just goes into an endless loop of Stream Closed, despite having sent and received a kick after reconnection.

The only thing that actually helps to reconnect is to restart the weron vpn ip process

command

# node 1 (nixOS laptop)
weron -v 6 vpn ip --community 'somecomm' --password 'strongpass' --key 'longkey' --ips 10.10.1.1/24 --static --dev weron0

# node 2 (nixOS homelab)
weron -v 6 vpn ip --community 'somecomm' --password 'strongpass' --key 'longkey' --ips 10.10.1.2/24 --static --dev weron0

logs from node1 (laptop)

Thank you for your amazing work btw! I find it quite fascinating that I can just setup a VPN between a few nodes in seconds without having to setup an account a website (zerotier, tailscale) or setting up discovery server (nebula, n2n).

This is definitely a bug, probably in the negotiation protocol. I'll take a look at this in the future, there is still a bit of yak shaving to do in the meantime (mostly in https://github.com/pojntfx/panrpc)
