When trying access clan error 319045

Good day. I am the head of the DarkKnights clan (EU). 2 or 3 days ago the clan stopped working:

  1. The clan chat does not work (error 319012)
  2. Clan players are not visible (there are 99 people in the clan).
  3. I can not accept new players to the clan - the option to accept a player to the clan is not active.
    Please fix the problem.
