Can't log in on my Mac

So I can’t log in.
on Teamspeak when I try to log in it says “Einloggen Fehlgeschlagen” and it just says that and nothing else need help quick pls.

Make sure your login in client is still valid and that you get no errors about the myTSID in your client log. Can you post your Client Log?

Please try to log in on the Official MyTeamSpeak or beta.teamspeak.com site.

When this not work, try to reset your password.

Otherwise, give us more logs or information.
