I have hit the very same error. My scenario is:
* Mosquitto is listening on port 127.0.0.1:X (tcp) and 0.0.0.0:X+1 (ssl) * I have ACL and users set. * Logins via SSL are authorized via certificate only and have no matching user entry, plus "use_username_as_clientid true", "require_certificate true" and "use_identity_as_username true". * SSL stations are FreeBSD with mosquitto 1.5.5 bridging local queues to Ubuntu central server * Local login via tcp is via user/login. * ACL is user1/topic, then user2/topic (for login/pass entries), then pattern for certificate users.There's no user/topic entry for any cert- based users. Local logins succeed, SSL logins are rejected with abovementioned "Socket error on client <unknown>, disconnecting." Downgrading mosquitto to basic 1.4.15-2 solved problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1815732 Title: mosquitto 1.4.15-2ubuntu0.18.04.1 "Socket error on client <unknown>, disconnecting."
