Friends have connection issues.

So my friends and I decided to make a server with the origins mod and the extra origins too. The server goes perfectly fine but it only let in the first 4 players who joined, and the rest of my friends that want to join can't do it and it says they have connection lost. It isn't a bad file thing on their pc or laptop nor their connection because this is the only server in which they cannot play. I've tried deleting their player files but it still doesn't work. If anyone has a solution or atleast the reason why that happens please tell me.

They probably don't have the same mod collection on their computer installed as the server.

Note that also versions of the mods and fabric must match

They do. We've checked and they do have the same version and everything seems fine at that point, but I think it's specially with them being new players in the server.

Share their client log and the server log of your server

About the client log, how can I do that?
Server log: https://mclo.gs/kbNutmF

One of their logs: https://mclo.gs/kdxKhBA
For now they're only two people with the same problem because they're the last two that have tried to join after me and other 3 friend joined.
