Resolution
This issue is caused by a regression included in release 2.401.2.3 (BEE-37051) which caused the managed controller using WebSockets as trasnsport to fail authenticating with the operations center. You can find a reference to this issue in a warning corresponding to the affected release in our Release Notes.
To solve the issue you might want to upgrade your operations center ane the connected managed controller up to version 2.401.2.5 or higher.
