502: Bad Gateway Node red Problems

Installation
21

Just installed Node_Red. Did not see a setting to disable HTTPS/SSL, getting bag gateway trying to open the UI. Where is this setting?

Hello, Hello
I also had this problem and was looking for a solution without success. I was able to solve the problem.

Back up HAss
Uninstall Node-Red
I renamed the folder in the config / node-red directory at: config / node-red-old
I installed and configured Node-Red
Bad Gateway 502 … disappeared …
:laughing:
Delete directory… config/node-red-old

I had the same issue. Looking at the logs, I needed to set:

credential_secret: secretkey

Maybe this will help someone.

How did you delete that directory, I have same troubles but could not even delete that directory.

Try this

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, 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, 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:

Configurations in Home Assistant OS 8.2 seem very different, many YT videos refer to earlier versions.

credential_secret: secretkey worked for me after trying just about every other suggestion in this thread, thank you for your suggestion.
