1.7.10 Custom modpack server time out issue

[Mechman]

I made a custom modpack through curseforge and it has run smoothly up until today. My friend times out every time he joins and it times out everyone from the server as well. The server is though bisect hosting and the modpack is up on the twitch launcher, its title is DaBoiZ Pack. I have tried resetting the server to backups from a day ago and even trying to delete all his player data from the server, he still spawns in the same spot with the same inventory for a few seconds and then everything times out. It is super frustrating and I could really use some help. And no, the issue is not from the sacred rubber tree he accidentally spawned. I removed it through world edit and he still times out.
