[SERVER:CastorServer][PID:65909][THR:139757060609792][Network Classes][Error][UID:0][SID:0][OID:0][MSINetReactorModern.cpp:505] SSL accept error : error:0A00010B:SSL routines::wrong version number

Cause

It is caused by incorrect configuration between Modeling Service and Intelligent Server. Modeling service’s TrustStore only contains one certificate of the Intelligent Server and missing the complete certificate chain (root certificate > middle certificate > Intelligent Server's certificate).
This command can be used to list the certificates which has been added in TrustStore:

keytool -list -v -keystore xxx.jks

Action

Run below command to add the certificate to Modeling Service's Keystore (xxx.jks)：

keytool -importcert -alias "xxx" -file certificate.pem -keystore xxx.jks

keytool -list -v -keystore xxx.jks
