Has anyone got a Problem with Minecraft Instance? I've updatet AMP on Unraid today and now i cant connect to the Minecraft Server anymore. I didnt changed anything i know and i'm connecting to the server the same way as before. Can anyone help?

I haven’t recently but this happened to me before here. Verify in amp which interface or up range amp is monitoring. Somehow that changed once for me. It was a simple drop down in amp. Not home to share or give you the exact wording though. 

I have created a dedicated UID/GID for this container, and trying to run it with those by setting UID and GID container variables to what I created (1500). However, these seem to get completely ignored, the container always starts as my main unraid user.

I also tried using docker extra arguments "--user 1500:1500" but then the container does not start.

 

Any advice on how to set the runtime user?

Im having CPU spikes with only a Minecraft Java Instance created but sleeping.

htop shows it being the command "ampinstmgr --silent ProcessPendingTasks"

I cannot find any Info anywhere to why this would be spiking the CPU usage every few seconds.

Does anybody have any Ideas?

Hey,
I am having issues with access to my AMP this morning. Looks like it is trying to update, but it seems that it is not working and I dunno what to do.

It is stuck on the following if i check the logs:

 

Any one a idea how to solve this?

or how i would force to use the us server?

Thanks for help

for anyone who has the same issue:

 

click on amp docker and user console and use the following command:

 

ampinstmgr --nocache upgradeall --mirror us-central

 

downloaded the update within seconds and amp is back running

The zip file download was an issue reported in the AMP discord. You were able to manually download it and place it in a folder to get the process past download.

 

Anyway, here to report that even though the license is set using an ENV variable, the AMP app itself forgets it on each restart. If you don't set it again in the AMP webUI then the game servers won't start, but doesn't clearly tell you that. Don't know why it won't use the ENV variable.

 

Edit 1: I redid the container by removing it's appdata but kept the same template. The MAC address is still set from before.

 

Edit 2: Looks like something to do with having the basic license set with ENV variable but I had upgraded the license the last time I ran the server. I reran the license setup and that seems to have fixed things as the license now sticks between restarts.

 

Edit 3: That didn't last long. Restarted to add a port and it lost the license again.

Hello,

 

if your AMP instances won't start after upgrade to unRAID 7 it is likely due to the license not working anymore. It was logged to my instances log:

[16:53:22] [Core Warning/1]       : Expected licence feature RunAMP is not present.
[16:53:22] [Core Error/1]         : No valid AMP licence was found. Please open a shell as the 'amp' user and run `ampinstmgr reactivate myinstance01` to reactivate this instance.
[16:53:22] [Core Info/1]          : Available features: )
[16:53:22] [Core Info/1]          : Active Licences: 

 

 

The reason for this is a bug with the --mac-address extra parameters:

I noticed this because of my router showing a new device and the old device with the old mac didn't come online after the day of the unRAID 7 upgrade.

 

 

How to fix:

1. run 

   docker inspect AMP

   from your unRAID shell
2. There will be two MacAddresses (your old one from the --mac-address extra parameter and a new one)
3. Copy the new one and overwrite your old one in the --mac-address extra parameter of the AMP Docker template and update container
4. Maybe confirm the MAC again with command, both MacAddresses should be the same now

   docker inspect AMP

5. When AMP is back up running, open a shell, switch to AMP user and reactivate your license(s) (find your license key in your AMP Docker Template)

   su -l amp
   ampinstmgr reactivateall

 

I saw that there was a security thing (Properbly FTP)

 

There is released a new version. Can we get this?

 

Thanks!

It's supposed to update automatically on container restart, or can be done through the UI. Let me know if it isn't working!

Oh yay I’m glad it’s working!  I used to put out a container update for every AMP update, but that was only cus I couldn’t get the built-in updater working. I eventually figured out how to make it work and so now I only push container updates when something is broken or new game dependencies are needed

Hello,

I've installed AMP and set it up.

My required instances are running, and I can connect to the servers.

But now I'd like to change the IP addresses of the individual instances and give each game server its own IP address.

Is this even possible?

Thanks in advance.

For those having issues with Project Zomboid (PZ). Took me a second to understand what was happening. If ports 16261 16262 and 27015 says Not listening, but you added them to the ports in the container settings and it's probably the first time loading, the startup will hang until you add a admin password. meaning, either add a password on the configurations or go to the console and type a admin password, to move forward, once that is completed you should be able to get the server working.

So does this CA update automatically on update release or does the docker image require to be maintained and updated manually before release?

Hello, I’m contacting you because I’m unable to connect to AMP. I purchased a lifetime license key.
I installed AMP Docker with my license key on Unraid.
I tried the first command:
“Please enter a value for the instance name,” and then I entered ADS01. The following message appeared:

[Error/1] No such instance matches the name: “ADS01”

Thank you for your help.

Edit:

Did you ever get to the bottom of this? I'm suddenly experiencing this a week later when I've had 0 issues.

Hiya! I have to say first and foremost, I LOVE that this is containerized.

The only thing I dislike, or maybe I am just bad at making it work: Is games like Ark that need WINE and it needing to be dockerized within the docker, is not possible. Which is fine, I host those outside of the AMP docker. Other than that, this shit just makes everything super simple!

However, I've recently been trying to make my server more secure and be robust, and with that I've drifted away from using Bridge mode for all my networks, and using custom networks for all my containers etc.

When I switch AMP Docker to its own container, it no longer can communicate and bind ports. Is this because it has its own network IP and I am port forwarding to the server and not the network/IP of AMP?

I have not set AMP up with a static IP itself, so I am not sure if that is the problem.

I appreciate everything by the way and thank you again for making this wonderful container!

EDIT: I've read through the thread and have found my answer. ^^ Thanks. :)

i can't get this to work at all, i create a minecraft java server and it says it's up and running but when i try to connect to the server on minecraft it says can't find server yet if i setup the same thing on crafty, it just works and that's free, what's going on?

Hi everyone! V24 has been released!

There is a very important data migration that needs to be completed BEFORE updating for people who are running these games: Satisfactory, ASKA, Saleblazers, or Sunkenland. Please view the release notes, which has instructions on what to do.

People not running those games will be fine not running the migration, but I would prefer that everyone take the time to do it if possible. Thank you so much in advance for your patience with this.

If you run into trouble you can post here or in this GitHub discussion. Thanks!!

It might be a port issue, can you show me your configuration for the container? Block out the password and license of course.

thank you for helping me, i have no idea why it's acting up, i have it fully port forwarded and working online with crafty4 and with crafty4 stopped and this started i just cannot get minecraft to see my server at all, whether that's using my dns address or local port.

also i did have it set to 8080 and just incase that was the issue i changed it to 8082 but that changed nothing.

the amp page itself works as intended.
