WSO2 APIM v3.2 | TLSv1.3 support for endpoint URL
Recently we have come across a requirement where the endpoint URL security has been upgraded from TLSv1.2 to TLSv1.3 and our API integration got broken with WSO2 APIM v3.2. Below is the summary of the incident and how I overcome this situation with support. Environment - WSO2 API Manager v3.2.0.221, RHEL 8.3, OpenJDK1.8.291 Problem Statement - API based integration got broken due to endpoint URL TLS upgrade to TLSv1.3. while WSO2 API Manager has a support with TLS1.2 only. We got the error as mentioned below- ERROR {org.apache.synapse.transport.passthru.TargetHandler} - I/O error: Received fatal alert: protocol_version javax.net.ssl.SSLHandshakeException: Received fatal alert: protocol_version at sun.security.ssl.Alert.createSSLException(Alert.java:131) at sun.security.ssl.Alert.createSSLException(Alert.java:117) at sun.security.ssl.TransportContext.fatal(TransportContext.java:311) at sun.security.ssl.Alert$AlertConsumer.consume(Alert.java:293)
