Continuing the discussion from Can't install node-red:
To summarize; I was modifying some flows in Node-Red for my outdoor lighting (wifi smartlife bulbs). I was testing a looping blink of some lights with a 5 sec interval and decided I wanted to change it to 10 sec and deployed the modified node while it was still running the 5 sec interval. I’m not sure if that part is relevant, but when I hit deploy it just spun the loading screen of node red for some time (usually takes 1 second). I actually had to refresh the page it took so long.
After that, I could no longer access Node Red, HA Supervisor tab, file editor, configuration tab and a few other aspects of HA. I restarted HA and each time was met with a Bad Gateway error on the node red web UI of HA. After multiple attempts to restart HA in different methods (core, server, unplug/re-plug) I still could not get into HA. Meanwhile; my outside lights were still accepting signals from node red and working in their sequential loop of my flow (not sure if it just had a backlog of commands it was working through). I then tried turning the lights off by the light switch until resolving the issue. I then figured I’d uninstall and reinstall node red since I had recently backed up my flows.
The problem now is that I do not have node red in my Add-on Store tab of the Supervisor screen. I also tried adding the proper github repository, “GitHub - hassio-addons/repository: Home Assistant Community Add-ons”
(which shouldn’t need done) and was met with an “Invalid repository” error. I also received the same message when adding “https://addons.community”.
*EDIT UPDATE: today I was able to add “GitHub - hassio-addons/repository: Home Assistant Community Add-ons” as a repo and install node red. However; after installation I’m still getting “502: Bad Gateway” when launching the web UI.
