I fellow https://wiki.teltonika-gps.com/images/f/f0/FMBXX_TLSDTLS_encryption_configuration_v0.2.pdf and use Self-signed certificate and upload to device,But when TLS1.2 HandShake,there are some error like below:
javax.net.ssl|FINE|63|nioEventLoopGroup-5-6|2023-03-14 17:17:45.899 CST|Alert.java:238|Received alert message (

How can I solve it?
Self-signed certificate is Supported?
