What is client Hello?
The ‘client hello’ message: The client initiates the handshake by sending a “hello” message to the server. The message will include which TLS version the client supports, the cipher suites supported, and a string of random bytes known as the “client random.”
What is TLS alert?
3.4 The TLS alert protocol The alert protocol is there to allow signals to be sent between peers. These signals are mostly used to inform the peer about the cause of a protocol failure. An alert signal includes a level indication which may be either fatal or warning (under TLS1. 3 all alerts are fatal).
What is encrypted alert 21?
You will receive the encrypted alert 21, if something is gone wrong in the SSL Layer(possibly data transmits).

What is the meaning of TLSv1.2, out, client hello?
What is the meaning of TLSv1.2 (OUT), TLS alert, Client hello (1) after the connection is closed, is it trying to reconnect? It’s not after closing, it is part of closing, i.e. it is after initiating close.
What is the meaning of this TLS output?
The callback curl uses to log protocol actions (when requested with -v) lamely decodes all records as handshake records (even though here it correctly identifies the record as an alert record) so it misdecodes the first byte as a handshake message type (1=Client Hello). Is it being sent by the server, or by the client?
Which is the correct version of TLS to accept?
A TLS implementation is supposed to accept any version that starts with “3” (TLSv1 is 3.1, TLSv1.1 is 3.2, etc). In practice, some servers will fail silently (instead of giving a useful alert) if this version is higher than they can support.
Why is my browser not supporting TLS 1.0?
The most common issue in this regression testing will be a TLS negotiation failure due to a client connection attempt from an operating system or browser that does not support TLS 1.2. For example, a Vista client will fail to negotiate TLS with a server configured for TLS 1.2+ as Vista’s maximum supported TLS version is 1.0.
