Hi @Codewow. Thanks for being part of GoDaddy Community! There isn't a restriction on the protocol in general, but ports are highly restricted on Shared Hosting plans. That might be what you're running into. Unfortunately, for security purposes, I wouldn't be able to provide you with a full list of what ports are open or closed. If you have a VPS or Dedicated Server, the options are greatly increased. Hope that helps.
