Error when trying to install Better MC modpack

[MasonMcGahey]

Hello, I am trying to follow the documentation and download a modpack for my docker server. When I look to the logs it seems to run fine for the most part a couple excluded mods, but I hit this error:

you won't find the answer here, these repos is bullshit that haven't been updated for months and years, i tried some examples, ten or above, none of the examples worked. Of all that is here, only one works - simple, without mods, which I can run without Docker with one command in the console

in each example you will find something like this:

Caused by: me.itzg.helpers.http.FailedRequestException: HTTP request of https://www.curseforge.com/api/v1/mods/289397/files/2960301/download failed with 403 Forbidden: Trying to retrieve file

Did you figure anything out? I'm running into the same issue

[ja49619]

the only thing I came up with was to deploy a container with a clean pure forge and add mods yourself, that’s how it works

[tannerdriscoll]

Do you have the yml file that worked for you I could use for reference? Not sure about the adding mods part.

[ja49619]

of course, this will work

  mc:
