Why am I getting "Matchmaking Error (#1)[1.1.2]" when trying to join a match in Fortnite?

We are aware of an issue where some players cannot join a match in Fortnite due to "Matchmaking Error (#1)[1.1.2]." We are currently investigating this issue.

In the meantime, we recommend switching to a different game mode and then returning to the mode where you received the error message to see if that helps resolve it.
