🐛 BUG: Unable to reconnect after server crash #1125
Comments
Also worth noting that this issue doesn't occur after a normal reboot. |
On the surface this looks like a nebula IP reuse issue but there's so much redacted that it's hard to understand exactly what is happening.
Both Host A and Host B appear to be attempting to initiate a tunnel with the other but neither logs show a matching handshake despite Host A responding. This means we should see logs on Host A responding to handshakes initiated by Host B. To help can you do the following:

Great, I've sent you an email. And there aren't multiple processes running. It's controlled by systemd. |

What version of
nebula
are you using? (nebula -version
)1.8.2
What operating system are you using?
Linux
Describe the Bug
One of my servers has been unstable and will sometimes become unresponsive, requiring a hard reset (this is host A,
172.0.3.109
). When it comes back up, it's unable to establish a connection to my node that is a nginx reverse proxy (this is host B,172.0.2.120
). If I manually restart the Nebula service on host A, it fixes the issue and host A can connect to host B.Logs from affected hosts
