After updating my Hyper yesterday, I started getting MQTT connection errors in Zendure Home Assistant (ZHA). Two firmwares were updated: a.- AC Firmware, now at version V2.1.17, and b.- MASTER, now at version 21.47. Since these firmware updates, the Mosquitto Broker has started showing this type of error in the log: 2026-06-17 10:28:31: New connection from 192.168.1.23:60957 on port 8883.
2026-06-17 10:28:31: OpenSSL Error while trying to get the error[0]: error:0A0000C1:SSL routines::no shared cipher
2026-06-17 10:28:31: Client 192.168.1.23 [192.168.1.23:60957] disconnected: Protocol error. That IP is my Hyper 2000.
