Origins not working properly

I made an origins/create modpack with my friend, and when we open a singleplayer world everything works out normally, but when we try to play a LAN server, if he's the host, it works out well, but the origins selection screen doesn't appear for me, and i'm invincible to all damage, and when i open a server to LAN, he can select his origin just fine, but i still glitch.
