Cisco WLC centrally switched SSID takes a couple of times before joining

Got a weird issue on the WLC. We have a new SSID that is configured wpa2, centrally switched using a psk that takes 2 times before joining. My linux laptop only took one try. I thought maybe it was the SSID but I tried some other SSIDs that are centrally switched and they also seem to have the same issue.

I ran some debugs and this is what it shows. If I removed the preshared key they connect right away. Maybe it's a timeout issue? None of our flexconnect ssids have this issue.
