Failure to cluster with livebook

[adiibanez]

I keep encoutering issues with livebook_tools. sometime everything works fine and it really provides value in the dev process.
but then it stops working for unknown reasons. At some point I thought that it might be depending on the network / wifi joined ... but that doesn't seem to be the case.

Any recommendations on how to debug further? Nothing changed on the configuration side:

livebook_tools watch proto.livemd

11:06:21.462 [notice] Protocol 'inet_tcp': register/listen error: econnrefused
