emqtt 使用 let’s encrypt ssl证书配置

Please also set cacertfile to chain.pem
You may also set certfile to cert.pem instead of fullchain.pem

listener.wss.external.keyfile = /etc/letsencrypt/live/xxxx.com/privkey.pem

listener.wss.external.certfile = /etc/letsencrypt/live/xxxx.com/cert.pem

listener.wss.external.cacertfile = /etc/letsencrypt/live/xxxx.com/chain.pem
