Hmmm... has it been hacked?

Any strange user regs before it went down?

Maybe you can review the last few users who roistered. If it is open. Just a thought. I've had NodeBB go down like that. No time to check it out. Nothing works like it should. Wasn't an important install.

How it woudl happen is, admin woudl approve a user. Since this would be an no users, this user is the first. Within about 2/3 mins of approving use.. BANG!

NodeBb goes down. Nothing is working like it should, in a similar way as to you are describing.

@nicolas

Can you try sending a request directly to NodeBB with curl on your server? (localhost:8081)

Where was that error reported? Nginx logs?

Posting the last few lines of your startup log isn't really helpful, can you paste the whole thing? Post a startup log from ./nodebb dev while you're at it for comparison.

Can you try attaching NodeBB to a different port?

Have you tried deleting node_modules and then npm install? On your version you might need to reinstall your plugins again.

@pitaj curl result is similar to Nginx

$ curl localhost:8081
Cannot GET /

Connection refused error that I have posted before, from Nginx Error logs.

Considering the situation, currently, I'm not messing with dependencies or configs that would work without any issues. I did not touch NPM Modules, did not try to remap port.

By the way, curl localhost:8081 for NodeBB that I run in Dev mode ./nodebb dev returns HTML, i.e. forum functions

What so special happens with the production start of the NodeBB that could stop working in such a fashion?

@omega interesting theory, I will see if any suspicious users were created last couple of days. But I'm the only admin.

@PitaJ thank you for brainstorming the potential issues. Here are full logs from NodeBB Start:

@omega Unlikely it was hacked, it's low profile forum.

Nicolas

Cannot GET /

Is it Express error output? Why would Express suddenly start to be unhappy about the environment?..

Nicolas

@baris any ideas what would be the most useful place in the main app to put the console.log to troubleshoot Express, why it does not blurp output?

PitaJ

@nicolas that is an express error, which is why I recommended reinstalling dependencies. I'm guessing this was just caused by a random file corruption that's only visible in production mode.

Nicolas

@pitaj is it possible? Does Express mutate its source files?

Touching Node Modules with such an old Node version without lock file can become very deadly for the forum and current setup.

<baris>

The files in node_modules could change if someone installs a plugin in the ACP. Does this affect all routes? Does loading something like forum.com/api/config work?

What active plugins do you have?

PitaJ

@nicolas huh? Mutating source files? I'm talking about cosmic rays flipping bits here.

Nicolas

@baris /api/config - does not work.

$ curl localhost:8081/api/config
Cannot GET /api/config

/api/config in Dev Mode - works

psychobunny

@nicolas though I don't want to immediately suggest you upgrade from NodeBB v1.0.2 (that's a LONG time ago! haha... welcome back btw!)

I wonder if you ran npm i etc and that upgraded you to packages that are no longer compatible with that version of core

Nicolas

I did not do npm install, I deactivated at this point 2 plugins that could depend on external services like Captcha and Twitch Monitor.

Here is an example of Express, if I would install node modules likely express would update also:

Nicolas

Any ideas why ./nodebb start does not work, and ./nodebb dev works?
Anything I could do to rebuild something in a less harmful way to try ./nodebb start?
Any suggestions why Express does not work in production mode?

Nicolas

So I'm debugging Express, in production, Route registration does not happen. For example, in debug mode I see logs like:

  express:router:route get /user/:userslug/edit/password +0ms
  express:router:layer new / +0ms
  express:router:route get /user/:userslug/edit/password +0ms

  express:router:route new /user/:userslug/session/:uuid +0ms
  express:router:layer new /user/:userslug/session/:uuid +0ms
  express:router:route delete /user/:userslug/session/:uuid +0ms

But in production mode I can see only initial Express operations:

That is why even the basic root route does not work since none of them are registered. Any hints where to look next?

@psychobunny @baris what am I risking by running forum as NODE_ENV=development ./nodebb start?

PitaJ

My guess is corrupted files. You can try setting up a new nodebb instance with a copy of your database.

Since it's affected by node_env it could be a nodebb file that was corrupted. Have you tried using git to detect a file diff?

Running with an ancient version of NodeBB is probably more dangerous than running in development mode. Might make MITM a little more likely.

<baris>

Can you post the output of git status as well?

You can always add console.logs into src/routes.js and webserver js to debug.

PitaJ

You might also want to try git diff --name-status HEAD^ as git status uses file size and modification time.
