Halo 5 multiplayer not working

The error message says could not find server suitable for all members of your fire team. It worked yesterday. Have turned Xbox on and off, unplugged Xbox, removed disc. Xbox customer service could not resolve last night.
How can I contact someone at 343 to resolve this? If Xbox can’t answer, will 343 get back to me with an answer please!!
