I have a forge server with around 200 mods and I would like to have it available 24/7. But instead of constantly having to run the server on a dedicated machine, I want to create a second server that a player must join to start the main server. The second server would permanently run on a lightweight computer which would transfer a player to the main server (or start the main server and then transfer the player when it is offline).
But the problem is that I cannot join the second server because "the server is missing the following mods [...]". Is it possible to ignore this error and just join the server? The second server does not need to have any mods (except for the handling of the transfer) because it should just act as a waiting room.
