ERROR failed to auto-install CurseForge modpack

[FabMaster2000]

Describe the problem

I want to create a SkyFactory 4 Server with the following command:

docker run -d -it -p 25565:25565 --name SkyFactory -e EULA=TRUE -e MEMORY=2G -e VIEW_DISTANCE=10 -e TYPE=AUTO_CURSEFORGE -e CF_PAGE_URL=https://www.curseforge.com/minecraft/modpacks/skyfactory-4/files/3565683 -e VERSION=1.12.2 itzg/minecraft-server

After some modpacks are successful downloaded the following error message occure:

Please re-pull the latest image and try that. The default SSL timeout is supposed to 20 seconds now.

[itzg]

...and if it persists, you can set FETCH_TLS_HANDSHAKE_TIMEOUT to a longer duration like "PT40S"

[FabMaster2000]

...and if it persists, you can set FETCH_TLS_HANDSHAKE_TIMEOUT to a longer duration like "PT40S"

now it worked better but there is a new error now:

[itzg]

You can also set FETCH_RESPONSE_TIMEOUT to something longer than the default PT20S. Your network seems to be suboptimal, so I would recommend also looking into that unless you are already aware of it.

[RazeLighter777]

Hey this is an MTU issue. I fixed this by setting my docker MTU lower. I set mine to 800.

[RazeLighter777]

For docker compose I added the following options

networks:
  minecraft:
    driver: bridge
    driver_opts:
      com.docker.network.driver.mtu: 800

And added

    networks:
      - minecraft

To the container

Thanks a lot. I will try it in a few days :)

After adding the line which is explained by the following lines:
https://github.com/itzg/docker-minecraft-server#fixing-unable-to-launch-forgemodloader

The modpacks were installed. But at starting the server after that, the following error occured:

[itzg]

You're using the wrong Java version. Refer to

https://github.com/itzg/docker-minecraft-server#running-minecraft-server-on-different-java-version

[FabMaster2000]

You're using the wrong Java version. Refer to

https://github.com/itzg/docker-minecraft-server#running-minecraft-server-on-different-java-version

Oh, doesn't mentioned that. I will try it with java8 / java8-multiarch

[itzg]

Ah, I actually am missing a check and warning for non-Java 8 with TYPE=AUTO_CURSEFORGE. I'll fix that.

Otherwise, yes, I do wish the Minecraft software would fail more gracefully with a version mismatch.

[FabMaster2000]

Is it possible to load the mods not via the command:
-e CF_PAGE_URL=https://www.curseforge.com/minecraft/modpacks/all-the-mods-8

but via a local zip? The zip for the SkyFactory-Server can be downloaded. Is it possible to migrate that?

[itzg]

Sure. There's always the old CurseForge mechanism and can fallback to generic pack if the server mod pack is "broken" like most.

[github-actions]

This issue is stale because it has been open 30 days with no activity. Please add a comment describing the reason to keep this issue open.

[Louis5487]

Hey, I still have the same problem even after increasing the FETCH_RESPONSE_TIMEOUT to a longer duration and setting FETCH_TLS_HANDSHAKE_TIMEOUT to something longer.

Here's my input:
docker run --name mc-mod -v /home/louis/mc-data:/data -p 25565:25565 -e EULA=TRUE -e TYPE=AUTO_CURSEFORGE -e FETCH_TLS_HANDSHAKE_TIMEOUT="PT120S" -e FETCH_RESPONSE_TIMEOUT="PT120S" -e CF_SLUG=all-the-mods-8 -e MEMORY=6G -e CF_API_KEY='....' itzg/minecraft-server

And here's my console report:

Thank you in advance for your assistance.

@Louis5487 I know stack traces all look like piles of noise, but you don't have the same problem. There is something not working with your DNS
