Unsubscribe path: /user/queue/message id: 186bf87b-3af9-449b-a41d-feb7ebab48b3

[covenant3717]

There are two android clients and one server.

Open a chat on clients (a connection to the server is made).

The first client sent the first message -> the second client received it.
The second client sends a message in response -> the first client did not receive it.
The first client immediately sends the second message -> the second client did not receive it.

Problem:
When sending a message to the topic "/ node / message" in the logs you can see the following "Unsubscribe path: / user / queue / message id: 186bf87b-3af9-449b-a41d-feb7ebab48b3".
And after that the topic "/ user / queue / message" is no longer observed.

Anyone have an idea what the problem might be and how to solve it?
