Cannot connect from HomeAssistant nor from LAN #374

Closed camedomotic-unofficial closed 3 months ago

camedomotic-unofficial commented 3 months ago

Problem/Motivation

I can't connect to my NUT instance neither from Home Assistant nor from any other laptop on my LAN. If I try to check the connectivity to the port 3493, it seems to be closed, even if the log says NUT is listening.

Expected behavior

  1. Setting up the HA integration to NUT, I would expect it to properly connect to localhost on port 3493.
  2. Trying telnet or nc on port 3493 of my HA server, I would expect to get a Port listening message.

Actual behavior

  1. The integration shows the error "Connection error: Multiple exceptions: [Errno 111] Connect call failed ('::1', 3493, 0, 0), [Errno 111] Connect call failed ('127.0.0.1', 3493)".
  2. I get a "Connection refused" error.

Steps to reproduce

I noticed that, instead of leaving blank (default value) the Network section of the add-on configuration page, if I set manually the port value to a specific number (e.g. 3493), then the server becomes discoverable and the issue is addressed.

Even if this workaround fixed the issue to me, I would recommend to fix the default port management (when the port number is left to its default, blank, value in the configuration) so that it actually works.

This fixes the issue:

Note: The host a0d7b954-nut can be used to allow Home Assistant to communicate directly with the addon.

Does this host not work when setting up the HA integration without exposing the port?

sinclairpaul commented 3 months ago

Closing this, it's documented and if you want external access to the addon it is within the UI, which the addon itself cannot influence.

bcutter commented 3 months ago

I'm facing the very same issue. With the slight difference, that setting the network port to 3493 still makes no difference:

So... what's wrong with the addon? How to locally check if the addon actually runs on the specified port? --> netstat | grep 3493 on the host (HA OS) gives nothing.

Do I need to open another issue or... can we re-open this one and clarify the situation?

sinclairpaul commented 3 months ago

As per the documentation https://github.com/hassio-addons/addon-nut/blob/main/nut/DOCS.md#home-assistant-community-add-on-network-ups-tools

Note: The host a0d7b954-nut can be used to allow Home Assistant to communicate directly with the addon

So use a0d7b954-nut as the host not localhost

This assumes that the NUT server is running and there are no errors in the logs.

bcutter commented 3 months ago

Thanks for pointing to that important information.

Unfortunately that makes zero difference:

The addon is running, latest addon log excerpt:

I have no idea what's wrong with the addon. Help highly appreciated. I'm trying for hours over several months to finally get this running.

Tested different usernames/passwords (maybe the password is not allowed to have certain special characters?), tried completely without authentication (leave front door open option), tested with network port configured/not configured, tried "localhost", "a0d7b954-nut", "a0d7b954_nut", ... NOTHING works. Debug log needed? I could not spot any suspicious in there.
