Does Caddy not support tls1.1?

My configuration is as follows:

https://127.0.0.1:7898 {
tls /var/sf/server.crt /var/sf/server.key {
protocols tls1.1 tls1.3
}
handle {
root * /var/sf/dist
file_server
}
}

However, an error occurred during start server and tls1.1 is not supported,the error is as follows:

parsing caddyfile tokens for 'tls': wrong protocol name or protocol not supported: 'tls1.1'

Now I hope my service can support TLS 1.1. How to do it, thanks

No, sorry, Caddy only supports modern TLS, 1.2 and 1.3.

TLS 1.2 is 16 years old. It’s time to upgrade your devices.

Just a note that while 16 years is a long time, it is still common that manufacturing equipment and related technologies are slow to adopt. Especially since 15-25 years is a normal life span for such machines :slight_smile:
