@lixmal, Hello. Yes, I've read it. It states that this error occurs if multiple users try to connect to NetBird from the same device, but the problem is that the user is alone. The connection is made via SSO Keycloak. This problem definitely does not arise due to the fact that users are different, there is always 1 user connected behind 1 device. The problem occurs unexpectedly.
I encountered a similar issue. Keycloak as SSO, operating system was Fedora 42.
