Livebook connecting to prod: Connection attempt rejected. Invalid challenge reply

Questions / Help
1

I have tried to connect from Livebook 0.9.1 to my prod env using app_name@one_of_machines_internal_ip + app’s cookie through Wireguard but got Node :"app@fdaa:0:...:2" is unreachable. I’m pretty sure it worked it the past.

I see in logs [error] ** Connection attempt from node :"livebook@127.0.0.1" rejected. Invalid challenge reply. **

There are two instances of the app, they connect to each other. Node.list properly shows the other node. I’m using the same cookie as shown by cat app/releases/COOKIE

What could be the issue?
