Solving your 502 Gateway Error with the Node-Red add-on for Home-Assistant Supervised (Hassio)
Really quick post. As a result of my 3 part Beginner’s guide to Node-red tutorials, some have reached out to tell me that they’ve been unable to run Node-red successfully. They have installed the add-on from the “Home Assistant Community Add-ons” section which can be found in the side bar under Supervisor => Add-on Store (tab), but when they start the add-on, clicking on the link results in a 502 bad gateway error. In layman’s terms, this http error means the webserver has received a bad response and cannot move forwards. In reality, it’s either you’ve tried to access the add-on too early or it’s usually a password / auth issue. I’ve helped several people to address this. If you’re receiving a 502 issue, binary options I would encourage you to wait a minute or so for Binary Options the add-0n to finish loading itself (you can check the progress on the log tab of the add-on). If you are still experiencing the 502 after a couple of minutes, I suggest you do the following.
Click on the conf tab of the Node-red add-on and basically paste this in. This is my configuration and it just works.
credential_secret: redacted but something difficult to guess dark_mode: false http_node: username: redacted but same as HA login password: redacted but same as HA password http_static: username: redacted but same as HA login password: redacted but same as HA password ssl: false certfile: fullchain.pem keyfile: privkey.pem require_ssl: false system_packages: [] npm_packages: [] init_commands: []
Now obviously, po.cash if you want dark mode or SSL etc., you’ll need to update this as required, but for now let’s try and get straight into node-red. Also some of this may or may not be necessary, Binary Options but as I mentioned before, this just works for me. If you want to go through the full configuration options, you can check here: https://github.com/hassio-addons/addon-node-red/blob/master/node-red/DOCS.md.
In order to preserve the correct lay out, here’s an example of it on the page:
A working configuration for the Node-Red add-on.
Save the configuration and restart. It’s normally a good time to refresh the page (holding shift) or clear the cache in your browser forcing a clean retrieval. If all went to plan, you should be staring at a fresh Node-red page waiting for you to unleash your creativity. Hopefully this saves you some heartache!
