  Hi,
  I think that, as described in the error, the problem is that the version of SSL is not supported by SSLClient; try to check the server security settings.

  Hi,
  sorry for the late response
  
  The error (SSLClient)(SSL_ERROR)(m_print_br_error): Incoming protocol or record version is unsupported. indicates that the SSL/TLS version the server expects is not supported by your client. Check if your server enforces a specific SSL/TLS version (like TLS 1.2 or 1.3). Ensure that your ESP32 or SSLClient library supports the required version.
  Try to modify the SSL settings on your server to allow older versions like TLS 1.1 or ensure the client can handle TLS 1.2+.
