I have a controller on v4.2.11 with 4 eap access points on it and all 4 would adopt this morning. Digging deeper it appears they have all randomly changed passwords and will no longer adopt...

I tried manually entering the passwords to adopt them and no luck. The web UIs are all pulling up now and the passwords won't work there either.... I have tried the default credentials as well.

Any idea what the heck is going on? I know for a fact the UN/PW I'm entering in is correct. Not only was it saved on my browser but there is a 5th device (pharros bridge) in the mix and I set all the UN/PW to the same thing. The correct credentials work fine on it. It's only the EAPs that were adopted into the controller that have magically changed... I'm sure I could factory reset them and readopt but this is a bit concerning. 

Any ideas?
