Original Pull Request: https://github.com/netbirdio/netbird/pull/5951

State: closed
Merged: Yes

Describe your changes

The Receive goroutine could outlive the test and call t.Logf after teardown, panicking with "Log in goroutine after ... has completed". Register a cleanup that waits for the goroutine to exit; ordering is LIFO so it runs after client.Close, which is what unblocks Receive.
