grepping the source for the environment variable shows it should have a url scheme at the end (http).

A bug among either their documentation or me.

6:43a adding the url scheme does not prevent the same fatal error message

6:46a it also needs the domain name resolved.

This launch string is working for me: FULLNODE_API_INFO="/ip4/104.21.75.210/tcp/1234/http" lotus daemon --lite
