Help to connect my friend on my local modded server

[Azot]

Hi !

     First I will prevent you : I'm not english, I'm french, so if I write badly, excuse me.

     Recently, I create a modded Minecraft server on my computer and I opened my internet box's ports. It's a server with All The Mods 7 0.4.25 (in 1.18.2), it's Forge 40.1.68. I gave the IP address to my friends who installed the modpack thanks to CurseForge. They can easily connect to my server. But, one of my friends is under Linux, and he has not access to CurseForge to install the modpack. So, I send the folder to him, he put all the mods in an instance folder for Minecraft after installing Forge 40.1.68. And, he can launch the game very well without bugs or problems. But, when he try to connect to my server, the game crash and we have this error :

(Sorry but I did not succeed to recover the entire error...)

ERROR
Game crashed
An unexpected error occurred and the game has crashed. We're sorry
for the inconvenience.
This crash may be caused by an invalid java
runtime configuration. Check any custom configuration
settings.
Exit code : 1

     We try to restart the game and we have this error thsi time :

 

     I looked for a solution on Google and I found one : delete the "modconfig" folder. So, I dit it, and, again, the game succesfully start but when he try to connect to my server we have a new error :

     This error have not sense, but OK, he reinstall Mystical Agriculture with the good version and nothing change, so I look for another solution and I found that it was necessary to also delete the folder "kubejs", so I also dis it :

     Yeah, it's worse... We resinstall Mystical Agriculture and KubeJS in the good version and we re-delete the "modconfig" and "kubejs" folders :

     Yeah, it's getting worse, now, the resources pack "Pack Menu" don't work and we still have the same error. So we reinstall the "packmenu" folder, nothing. So we redid everything from the beginning but, this time, I never played on the Minecraft instance that I gave him. This time when he try to connect to the server, he's connect from the server side, but, on the client side, he stay stuck in the loading with this message "Loading terrain". He stay stuck so long that the server kick him. I have not found any solution. Can you help me ?

Tell your friend to download the zip from CurseForge himself/herself. There are probably additional configurations/settings that are in that zip not in the mods folder you provided. You do not need the launcher.

When we download the .zip from the CurseForge website, it not contain mods but a file "modlist". Will he be able to read it ? I will try anyway.
