Version too low?

[theoparis]

Error: 28112:error:1420918C:SSL routines:tls_early_post_process_client_hello:version too low:c:\ws\deps\openssl\openssl\ssl\statem\statem_srvr.c:1661:

These are my settings:
secure: false,
ciphers: "SSLv3",
minVersion: 'TLSv1',

and the port is 25

I don't know how to fix this, I've tried multiple ports and security levels and it just says its too low.

Have you tried it with a secure connection and a Let's Encrypt SSL certificate ?
