Troubleshooting Forever and port 4567

finid

Finally. After 4 days of frustration, I can access my installation of NodeBB.

Here's the output from the startup log

And port 4567 now shows up in the output of nmap and netstat.

How did I get to this point? Uninstalled most of the plugins.

Next step? See if I can access it from a subfolder via Nginx proxy

Succeeded in accessing it from a subfolder via Nginx proxy. Aside from a few issues, like images in existing posts not showing and sound notification not working, all seems fine.

I just have to figure out why existing images in posts are not showing.

julian

Awesome -- double check what URL those images point to. If they're existing images, I'm thinking they don't have the subfolder in the URL.

finid

If they're existing images, I'm thinking they don't have the subfolder in the URL.

True, they don't, because before yesterday, I was accessing NodeBB by appending the port and subfolder like this: site.com:4567/forum. How do you suppose I can fix that now that I'm accessing it via site.com/forum.

I have a lot of images already.

julian

Accessing an image with the port should actually still work (unless the port itself is closed to the public, that is)... the tough part is there's no way to fix the URLs now... no easy way, that is...

finid

@julian

That doesn't sound good. I don't really care if the way is easy or not. Do you have any suggestions in mind?

finid

@julian

The situation with images is this: existing images don't load and new images also don't load. If I attempt to insert an image, I get something like this: ![barts.gif](uploading100%). It never loads.

Now, the path for existing images is something like this: http://www.site.com/uploads/upload-67cc0ef9-0ea4-4d73-85ef-4521116b7cc5.png. That's from the time I was accessing the site using its port number, before Nginx proxy came in to play.

Now, the current image url is like this: http://site.com/forum/topic/153/uploading100%. The image never completely loads.

Even after changing the upload_path from the default to "/forum/public/uploads", it still does not work

Do you have any ideas why and what can be used to solve this?

Something weird happens in the process uploading an image, as shown in this screenshot. It's visible for about 2 seconds before it reverts to normal.

Luciano Miranda

@planner I have the same problem. When my home page is visited, nodebb send a [ "ws://..." 502 bad gateway ] on chrome console, and widgets are not loaded.
But after user click on any link, the error not occurring any more
I'm using nginx proxy bypass.
How you resolved this?

Thanks

@Luciano-Miranda

Because I have tons of images on the site that I could not use when accessing the site from a subfolder, I decided to run the site from a subdomain. So I abandoned the subfolder route.

Luciano Miranda

@planner What is your config.json and ngix.conf?

Ps: I have used mydomain in this post instead of my real domain

my config.json:

{
      "base_url": "http://www.mydomain.com",
       "port": "4567",
       "use_port": true,
       "secret": "-",
       "bind_address": "127.0.0.1",
        "database": "mongo",
                   "mongo": {
                          "host": "127.0.0.1",
                          "port": "27017",
                          "username": "-",
                         "password": "-",
                          "database": "-"
                },
       "bcrypt_rounds": 12,
       "upload_path": "/public/uploads",
       "relative_path": ""
}

And my nginx.conf

  user www-data;
  worker_processes 4;

            tcp_nodelay on;

        }
    }
}

When user access the website, chrome send this error:

julian

What version is your nginx server?

Luciano Miranda

@julian Version 1.4.1, ubuntu server on amazon ec2

@Luciano-Miranda

If you set ***relative_path to /forum and proxy_pass to http://127.0.0.1:4567/forum, it should work, but likely with the problem I had uploading images.

And if that is the real secret in your config.json, you might want to remove it.

Luciano Miranda

@planner I'm using a single domain on my ec2 Instance...
So, i really need to set a relative path?

That error started after to cloudflare dns pointed to my Elastic IP. Using only IP address, this error not occurred.

I need to set other config on nginx, like a site available or something else?

julian

Make sure your cloudflare domain record is not CF accelerated (grey clouds, not orange). They interfere with web sockets...

Luciano Miranda

@julian Solved... I changed my DNS server, i think that cloudflare cache was the problem origin.

@finid How did you resolve the image not showing? I dont even get a preview when typing. It only display the links. I can see that you have changed the preview tab?
