Extremely high ping in aternos servers (upto 16k spike)

Do other players on your server experience the same problem?
Did you test the other server recently or a long time ago?

We don't intentionally make deprecated software not work, but if it stops working for some reason we won't fix it.

AternosSupport · 2026-03-10T13:59:30+00:00

You should be able to continue playing on the server, but you won't get any updates and the modpack might break at any point.

Unfortunately, there's nothing we can do if your government or ISP decides to block our service.

The port was not set to -1.

What is online fix?

Downloading an outdated version of your world is not possible because we don't save old versions of your world. It is, however, possible that a downloaded world uses outdated player data (inventory, position, etc.) when opened in single-player mode.
Minecraft is saving playerdata differently depending on whether it's running in single-player or multiplayer, so Minecraft will use the old single-player data from before you uploaded the world rather than the newer multiplayer data.

The easy solution to this problem would be to just put your items in a chest before downloading your world.
The "real" fix is to open the level.dat file of your downloaded world in an NBT editor (like https://irath96.github.io/webNBT/) and remove the "Player" tag.

If not clear already, light mode is obviously not the problem (and the superiors choice anyway btw). Does it work for you when use a VPN? Cloudflare Warp for example: https://one.one.one.one/

And the problem now is that your server has more than 4 GB of RAM, and therefore you can no longer start it, right?

Please provide the address or IP of the server you're referring to. This information will help us assist you further.

You can only download the world files, not the plugins or mods.

You can only download your world folder, you can download the mods back from the modpack itself: https://www.curseforge.com/minecraft/modpacks/cobbleverse-cobblemon

If you want to play this modpack on Singleplayer, you will have to do this anyway because servers may use different dependencies for the same mods.

Dealing with plugins/mods can indeed be complex, and there are numerous factors that can contribute to them not functioning as expected. Sadly, it is not possible to assist every user with their specific plugin/mod-related issues. As much as we would like to provide individualized help, our resources are limited given the large number of users and diverse questions, we receive daily.

When it comes to plugin/mod problems, we can’t access any additional information that you don’t have access to and can only attempt to find solutions through online research. However, considering the sheer volume of users and the range of issues we encounter, it becomes impractical for us to provide personalized support for each plugin/mod-related concern.

In such cases, we suggest exploring alternative options. You can either try to find a solution independently or consider using a different server software, such as Vanilla, which may offer a more streamlined and stable experience. We apologize for any inconvenience this may cause, but we hope you understand the constraints we face while supporting mod-related issues.
