Cant enter lich king raids

I can not enter any of the wrath of the lich king raids or dungeons, it worked last week before the update and now I can’t enter any of them, I have tested the entrances to other raids like seige of ogrimmar and those ones work but not any of the lich king ones

I know this probably isn’t the problem, but are you trying to enter the instance on a boosted toon? Freshly boosted characters can’t enter legacy raids for a little while after they’re boosted.

no, i had this character at max for about a year now
