Hi, I've been combing through other peoples posts that are similar to this error but I can't figure out how to fix it? Any suggestions would be greatly appreciated.

Health Overlay (healthoverlay) encountered an error

Attempted to load class net/minecraft/client/Minecraft for invalid dist DEDICATED_SERVER

You're trying to load a client side only mod on the server.

Also, contact the mod's author, not us.

I'm contacting this forum because the modpack (Valhelsia origins) I modified because I wanted to add a few more mods for player experience. I probably should have said that in the original post but this is my first time using this forum. Contacting the pack author would be pointless since I've changed the original pack. I've deleted health overlay from the server file and I'm still having connection errors.
