Can’t Join league match in Clubs – “Failed to Join Lobby” - Clubs

Every time I try to play Clubs mode with my friends, the game starts searching and then shows the message “Failed to join Lobby!”.

When two of my friends play together, the match starts for them normally — but I’m always the only one who can’t join.

I’ve already restarted the game and console, checked my internet connection, and made sure everything is updated, but the issue still happens every time.

Please help me fix this problem so I can join matches with my friends again.
