Connection refused about minecraft-nodebb-integration

[yariplus]

Are you using SSL? I have not tested this without SSL.

[Couby]

That's it, yeeeaaahh. 😊

I simply added an entry in /etc/hosts to force routing the https://[my forum url] request from MC Server to my local proxy machine.

Now that works :).

[Couby]

Yes I'm using it on NodeBB side.
But not on Bukkit server side.

[yariplus]

Could you post the your config.yml, without the apikey and messages section?

[Couby]

Yep :

forum:
  url: *https://myforumurl.com/*
  name: *MyForumName*
  apikey: *my_API_key_from_NBBForum*
socketio:
  address: *https://myforumurl.com/*
  transports:
  - polling
  - websocket
  namespace: plugins.MinecraftIntegration

[yariplus]

Thanks.

Does opening https://myforumurl.com/ in the browser get properly redirected?

What CA are you using? (Let's Encrypt, StartSSL, etc..) Are you using cloudflare at all?

[yariplus]

I'm trying to reproduce the error. The only way I can make it happen so far is when the forum url is misspelled.

[Couby]

I'll check again the config.yml and will also try with volontary misspelled url to see if there is a difference on my side.
Could you share also your config.yml, without the apikey and messages section ?

[Couby]

Misspelling the url I have a different error message :

[19:14:13 ERROR]: [NodeBB-Integration] Can't connect to forum at https://minet4c.osezlejeu.co/
[19:14:13 ERROR]: [NodeBB-Integration] Use `/nodebb url URL` to set the forum address.

Trying to set the url this way give me the following error :

[19:14:49 INFO]: Unknown command. Type "help" for help.

[yariplus]

Sure thing

forum:
  url: https://yaricraft.com/
  name: '&aYaricraft Forums'
  apikey: seekrit
socketio:
  address: https://ika.yaricraft.com/
  transports:
  - polling
  - websocket
  namespace: plugins.MinecraftIntegration

I use a different socketio address because I use cloudflare, but yours should be the same as the forum url.

[yariplus]

nvm, I see you misspelled it on purpose, dang, that's very weird.

Something is going wrong with the url format, looks crazy, sorry with this strange issue.

[yariplus]

You mean the 4 is causing the /nodebb url command to fail?

[yariplus]

Is the mc server running on the same machine as the forum? Maybe the issue is with port access as you originally suggested.

[yariplus]

Yep, same machine as the forum, also on a non-standard port.

[yariplus]

I can connect successfully to your forum from my machine, so I can only think it's some setting in your box. I can't imagine what it could be though.

[yariplus]

Nope, that all looks normal.

For the server IP field in the forum, this should be the server domain name, as it is only used for user display. The forum never connects to the mc server, only the mc server to the forum. The error just means the mc server has never connected.

I think you need root to read the access.log and error.log files. See if you can see them that way.

[Couby]

You mean mc server logs ?

I moved the forum and mc server on the same machine. I'm using http://127.0.0.1:4567 as url and socket live adress.

Things look a bit better. I don't have the error message anymore. But using nodebb toggle command I see the forum is not connected :

[22:16:18 INFO]: The server is currently DISCONNECTED from the forum.

[yariplus]

Well, that's something I guess.

Try
/nodebb debug toggle
/nodebb reload

[Couby]

Here is what I get, with a /nodebb debug just after :

nodebb reload

My setup :

• NodeBB v1.1.2
• CraftBukkit version git-Bukkit-6053c5c (MC: 1.10.2) (Implementing API version 1.10.2-R0.1-SNAPSHOT)
• Vault v1.5.6-b49
• OnTime v4.1.4
• NodeBBIntegration v0.7.3

System :

• Debian 8
• java version "1.8.0_101"
• node.js v4.5.0
• redis 3.2.3

[yariplus]

I'm guessing that is from using the localhost address. I am getting a valid cookie using the full domain from my PC. I'm not sure why you can't use the domain from the same machine.

What is the result now after /nodebb url tnc.osezlejeu.com

[Couby]

What is the result now after /nodebb url tnc.osezlejeu.com

The same error :( :

[06:52:04 INFO]: Set forum url to tnc.osezlejeu.com

Maybe I should try to reinstall "MC server"...

[Couby]

Tried with a vanilla server on my local computer. It works.

So I tried on the CT with a vanilla server. Doesn't work...
That makes me think could be because it is a CT... will try with a VM.

[Couby]

... will try with a VM.

Not better 😊 .
Clearly a local network setup issue...

[yariplus]

That's what I'm leaning towards. I just don't have enough network knowledge to tell you where to look for the problem.

[Couby]

Thanks anyway.
If I find a solution, I'll report about it.
Maybe my next attempt will be a local DNS to route correctly the https forum request from mc server locally...
