This worked for me (got the idea from this post):
- run
fly config save -a <name of the Livebook app>
in an empty directory - in
fly.toml
, add the following line to the[env]
section:
ERL_AFLAGS = "-proto_dist inet6_tcp"
(there was already a line elixir_erl_optio_ns = "-proto_dist inet6_tcp"
in this section, but (a) there’s a typo? and (b) even w/o the typo, it seemed to have no effect?)
- run
fly deploy -i livebook/livebook
Once the app is redeployed, Livebook should be able to attach to other nodes.
