It might not be much help in debugging, but I went through the server log and noticed a few things. They might be of use to someone looking into this after me.

I'm not sure to the cause of the issue, but we have seen similar connectivity issues with clients running with just (not) enough RAM. Client seems to be connecting for a long time and crashes at the last time during load or kicks user from the server after connecting. Not sure though.

Maybe any of the mod pack devs who have been around longer can add to this?

Fyi: I'm running a EU-server with just EU-clients. This might also be caused by a wonky internet connection on either end. Not sure.

Can anyone join the server?

What I meant is, are other players able to connect to the server, or do they get kicked as well?

You set RAM allocation in the settings file.

Alright. Well the crash is fairly common, it can happen because of a bad internet connection on the client side, client lag, the server not having portforwarding configured, server side firewall, client side firewall... A host of things, that are not modpack specific. I'm going to close this issue and relay you to the discord for support :)
