I am getting a Encryption alert from the Server and connection resets

edit

Hi Thanks for your reply.

Actually my traffic flow is Client--> proxy --> Server. in the flow client and server is exchanging the application data, at some point Server is sending Encrypted alert (21) is sending to proxy and so proxy is resetting the connection, so proxy sends back gateway timeout to the client. here why server is sending this alert in the middle of application data transaction. thanks in advance.

As said, most of the times, a "Encrypted Alert" record contains the "Close notify" message. To be sure what's inside the "Encrypted Alert" message you need the plaintext.

If your client application is a browser (e.g. Chrome or Firefox) you can give it a try with using SSLKEYLOG (s. https://www.youtube.com/watch?v=bwJEB...)

I am getting Encrypted Alert (21), when client attempt to send app data to server, this happens in following order client hello server hello, certificate, server key exchange, server hello done client key exchange, Change cypher spec, encrypted handshake change cypher spec, encrypted handshake (from server) encrypted alert

I could not decrypt. But wondering what could go wrong after cipher negotiation and encrypted handshakes Appreciate Any help

Did you ever figure what the problem was?

I am getting the same Alert 21 sent by the client instead of Client Key Exchange, Change Cipher Spec Encrypted Handshake
