What is the cause of the "SSL routines:ssl3_get_record:wrong version number" error when connecting to a Hetzner mail server using the "imap-simple" package in Node.js IMAP client?

edit

The "SSL routines:ssl3getrecord:wrong version number" error indicates that the SSL handshake between the Node.js IMAP client and the Hetzner mail server failed because the client and server are using different SSL protocols or cipher suites. It is possible that the client is trying to connect using an outdated SSL protocol or cipher suite that is not supported by the server. To resolve this issue, the client should be updated to use a newer SSL protocol or cipher suite that is compatible with the server, or the server settings should be modified to support the client's SSL protocol and cipher suite.
