Can't queue for Flashpoints – "You are in a conflicting phase" bug

Hello,

I am unable to queue for Flashpoints because the game says:
"You are in a phase that is in conflict."

I have already tried multiple solutions, but nothing has worked:

• I abandoned all Flashpoint and Operation quests
• I traveled to multiple planets (Imperial Fleet, Nar Shaddaa, Dromund Kaas)
• I completely restarted the game and logged in again
• I tried using /resetphase, /stuck, and /leavegroup in chat
• I only have one character, so I cannot test it with another

I can queue for PvP and solo content, but I cannot join group Flashpoints.

Character Name: Satoriy (lvl 51, just finished the class-story)
Server: Darth Malgus

Does anyone know how to fix this, or can a moderator check if my character is stuck in a broken phase?

Thanks in advance!
