Lotus Version

Daemon: lotus version 1.29.1+mainnet+git.3a3395d

Repro Steps

  1. Start the lotus daemon with env variable LOTUS_API_LISTENADDRESS set to /ip4/0.0.0.0/tcp/1234/http.
  2. Also set the daemon --api setting as --api=1234.
  3. Attempt to reach the API endpoint from an external source, e.g. another machine, on the same network.
  4. Get Failed to connect to <redacted IP>: Connection refused.

Describe the Bug

Hi there!
I'm new to this space and I found a potential bug when setting up a Lotus full node. My issue was that when I tried to connect my Prometheus (running on another machine) to the Lotus node, to scrape its /debug/metrics endpoint, it was not getting through.

What I found was that the --api=1234 CLI arg to the lotus daemon command overrides the env var I had set for the service running the daemon. It both overrides the env var's port and address, even though the setting only is for the port. E.g. even though I had specified 0.0.0.0 for the listen address in the env, it still ended up being 127.0.0.1:1234.

I don't know if this is intended or not, but either way it would be helpful if the lotus daemon prints what address/port it listens to when starting (kind of like the gateway prints setting up API endpoint at 0.0.0.0:2346). And perhaps even more helpful if a warning is printed in case an override occurs.

There aren't really any logs directly connected to the issue so I'll put the startup message from lotus daemon below.
