When I open the "organizer" in xcode 6.3.1 I get the following error message and am unable to submit or verify my apps:
"Unable to log in
Unable to log in with accounts
account1@test.com, account2@test.com, account3@test.com
Open the account preferences to check your usernames and passwords"
All these accounts were working a week ago and I didn't change anything. Also I double checked some of the accounts usernames and passwords and they are still valid (I event tested a couple of them by logging into iTunes Connect with the credentials). I am currently unable to submit or verify my apps, any ideas?
