I have tried everything to my knowledge at one point I just opened all the ports, I have my mysql port allowing all TCP connections on the default mysql port, the mysql db is on the same server as the servers, should I use localhost as the address? This is my config
Is it a linux server? If so run this command in the command line: netstat -tlpn | grep mysql
The out put should look like this:
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 5921/mysqld
The 0.0.0.0:3306 in this example case is the IP and port the MySQL server is listening to. If it is 0.0.0.0 use 127.0.0.1 in your LP config. Also make sure you use the right port in the config.
And a pool size of 10 is a good value.

Not a Luckperms issue. http://lmgtfy.com/?q=Communications+link+failure+mysql
Next time - actually read the error message first.
I looked it up and I only got things for developers as in writing plugins, and I combed the error several times, I shouldn’t have to under stand all the java and MySQL errors just to run a plugin the way I want, that google search only turned up things that had no relation to what I was doing.
Please read the last section of this page: https://github.com/lucko/LuckPerms/wiki/FAQ
Also try replacing localhost with 127.0.0.1 as localhost might translate to ::1 (IPv6 localhost).
It still didn't work for me ;/ I also have my servers running on a dedicated server under 0.0.0.0 could that have anything to do with it?
I did this and it's listening to all ips from all ports and on 3306
@lucko Can you please open this I think @BrainStone is right, I do run the minecraft servers inside docker
@Samkist This is still not a LuckPerms issue, but rather a problem with your setup. If you run the minecraft server in docker then the database IP should not be 127.0.0.1.
Does your MySQL server also run in a docker container? If so then the hostname should be the network name of that docker container.
Does it not? Then please see this thread on how to setup so it can access the host or google "docker connect to host". https://forums.docker.com/t/accessing-host-machine-from-within-docker-container/14248/9
I found this but I don't know if my docker container has an IP?
docker network create -d bridge --subnet (ip)/24 --gateway (other ip?) dockernet
@Foorack
@Samkist This is confirmed not to be a LuckPerms issue. I don't think this is the correct place to continue discussing this. For more help I recommend you asking on the Docker Forum or with whoever configured your Docker setup. It is important to note that 127.0.0.1 does not point to the host machine, only to the virtual docker container itself. While Docker containers are not virtual machines, they are completely isolated when it comes to networking.
If your MySQL is running on the same host machine then you need to find a solution to connect to the host machine from inside the docker container. This is not the easiest and it is therefore recommended to run everything-containerized or containerize your dependencies (databases, etc) first.
There is currently no "correct" way to connect from a container to the host as this violates the principle of isolation in the first place. See this StackOverflow answer and the links it mentions for more information: https://stackoverflow.com/a/28058549 But the way you have to do it depends on the version you are running, what network stack you are running, what operating system you are running it on, etc...
I am curious why you are running a Minecraft server in Docker in the first place. I am a developer for a server where we are currently in the process of deploying Docker to everything on our network but that is purely for scaling purposes as the number of individual servers has now become slow to manage. Does using Docker make sense for your setup? If you want to continue using Docker for whatever reason then your best bet is to containerize the MySQL database as well. That way you can specify the host as the name of the MySQL container. If you do this then remember data inside docker volumes are not always persistent, and storing the database directly to the hard drive is highly recommended. 👍
@Foorack I have a panel that creates the Docker I do not know if it does it inside all one Docker or in multiple to contain the ram but I use it the panel http://pterodactyl.net, I believe the panel or it’s daemon “wings” inits the Docker container so idk if Docker run would work and I am not exactly far along in the tech world as I am 14 so the best I can do is try to understand commands but I’m having some trouble.
@Samkist Ohh, you use pterodactyl, it makes more sense why your Minecraft server is containerized then. I'm sorry I have never worked with that panel in the past so my knowledge in that area is limited.
In that case, I recommend you to contact them as they surely have had this topic before. At the top of the Spigot post, there is a Discord (they will most likely answer fastest there) and a Github link. This is not a LuckPerms specific issue, tell them you have a plugin which wants to connect to the MySQL server running on the host machine, but it can't because the server is containerized and therefore can't connect. They should from there be able to guide you. Good luck. 😃
Thank you @Foorack!
