I found a previous issue that sounds simular: https://github.com/Skidamek/AutoModpack/issues/130

Check list

• [X] I have verified that the issue persists in the latest version of the mod.

I have found a problem similar to the current one I turned off generateModpackOnStart on the server.

After restarting the server it doesn't seem to get the automodpack-content.json content correctly (I'm not sure about this).

The client joins the server without a download prompt, but when the administrator or console enters the automodpack generate command to regenerate the automodpack-content.json the client tries to join the server again and gets a prompt.
