a fatal error has occured, connection terminated

[GhoastBee]

so i made this modpack but when i start up a world it tells:a fatal error has occured, connection terminated 

heres the dropbox:https://www.dropbox.com/s/bprfmbecazkeb3v/modpack.zip?dl=1

yes i do know the mods are from a bad source but thats not the problem isnt it?

ill switch to mods from curseforge after i manage to get this to work

also there are some conflicts still in the dropbox i sent but not in the game files i have on my pc so maybe thats the issue

this is what i got on logs (what i believe is the problem):
