HTTPS broken after upgrade to 15.3.1 (from 15.3.0)

I have Snap and upgrade our FTP server yesterday from 15.3.0 to 15.3.1

now https is no more working.

This site can’t provide a secure connection

ftp01.tsiss.com uses an unsupported protocol.

ERR_SSL_VERSION_OR_CIPHER_MISMATCH
view certificate is fine and valid.
any idea ?

  • Thanks , yes I did that exact check and SSL Labs simply said it could not connect. Think by default TLS1.1 is no longer supported in 15.3.1 so I wonder if certain certificates if they are old dont have capability to work with TLS1.2 or 1.3, seems odd but thats the only explanation I could think of?
