I am making a hide and seek map. To do this, the killer must be on team 'Blue'. I put in this command:

/scoreboard teams join red @p

And the command block says

Could not add 1 player(s) to team red.

I am curious why it isn't working as it doesn't give me a reason. Does anyone know the cause? How do I fix it? What do I need to do?

In order to join a team the team in question must already exist.

First create a team (or more):
/scoreboard teams add <name> <display_name> (display name is optional)

You can as well list your current teams to check what's already there:
/scoreboard teams list

And if you use the list command with a team name you can check what players are on that particular team:
/scoreboard teams list <name>

If you have your teams you can then finally add entities to them...
You can use selectors [@a, @p,..] for the entity or even leave it blank (in that case the executor will join the team)
/scoreboard teams join <name> <entity>
