I am having trouble connecting to RabbitMQ

[strDONGLION]

I want to host a BeatTogether server on Linux Ubuntu, but I'm having trouble connecting to RabbitMQ and getting errors. I've tried several things, but I think there's a good chance I'm doing something wrong because I don't know the details of hosting. Here's what I tried:

1.Download the BeatTogether.MasterServer image.
2.Setting up appsettings.json.
3.Blocking ports 5672 and 15672.

Here's the appsettings.json:

{
  "MasterServer": {
    "EndPoint": "192.168.10.187:60160"
  },
    "Serilog": {
      "File": {
      "Path": "logs/BeatTogether.MasterServer-{Date}.log",
      "FileSizeLimitBytes": "33554432",
      "RetainedFileCountLimit": 8
      }
   }
}

And here's the error log:

And, I am sorry if it is rude or inappropriate to you since I am using the online translation site.

It is because you only ran the MasterServer. There is also RabbitMQ, DedicatedServer and StatusApi server you have to run at the same time to make it work. Oh and base on the log, your json is malformed as well.

There is a reason why I made it using docker-compose. So, unless you know what you are doing, please follow the guide and don't skip steps!

Thanks for pointing this out. I think I was overcomplicating things and got confused trying different approaches. Thanks to your help, I was able to get the server up and running, but now I'm having trouble creating the server due to a connection error(CFR-9). I think the configuration in the JSON file is probably incorrect, but could you please explain more about "EndPoint", "HostName", and "Urls" in master.json, dedicated.json, and api.json? Specifically, I want to know if I should enter a local IP address like IPv4, a global IP address, or something else. Also, if I leave the sample config as is, will the port used for public access be 2328?

Specifically, I want to know if I should enter a local IP address like IPv4, a global IP address, or something else.

In the readme, I've already specified the meaning of every single address in the json files. Please take a look. Maybe I need to add more explanation.

To be honest, you at least need some basic knowledge of server hosting and the bare minimum of networking to understand what is "the ip to listen on" and the other terminology.

Usually, if an ip is used for a server to listen on, you can use 0.0.0.0 for it to listen on all the ipv4 addresses that your system has. This may not include your public ip and therefore you may need to configure port forwarding in your router as well.

Also, if I leave the sample config as is, will the port used for public access be 2328?

If you leave the sample config as is, it would be 2328, (as of the new gamelift change, it will be 8989), but no one will be able to connect to the server. because in the dedicated.json, you need to use the correct public facing ip
