Hi Team, We had to make our flink env hardened to use the desired security.ssl.algorithms and security.ssl.protocol in the internal and rest communication. Everything worked fine till we had to use a cipher which is not in the java defaults and it truned out that protocols and ciphers are not set everywhere. So, I'd created a Jira ticket related to use the same SSL protcol and algorithms on all the flink services and all clients . I have the fix downstream, but I think it would be useful to submit to the upstream as well. Please take a look and Thank you! Br, Jozsef
