Hi @Luciferdowny. Welcome to GoDaddy Community! If you're using our cPanel Hosting (which is a shared environment) you would not be able to close or open any ports. If there's specific traffic you're trying to block, you may need to find another way to do it. If you can provide more information, maybe someone else in the community can give some suggestions.
If you have a VPS or Dedicated Server, you can usually open or close ports with admin access. If you need help with a VPS or Dedicated Server, you may want to post a topic on that board.
