Description

I saw #260 but there was no solution and I don't know if it's the same issue.

I'm trying to connect via FTPS to my server.

I was getting: Cannot connect to server: Non-anonymous sessions must use encryption.

So I set tls to true.

Then I was getting: Cannot connect to server: tls: first record does not look like a TLS handshake.

So I set insecureSkipVerify to true.

However, I have the same problem.

The server section is like this:

server:
  ftp:
    host: <ip>
    port: 21
    username: <user>
    password: <pass>
    sources:
      - /source
    timeout: 30s
    disableUTF8: false
    disableEPSV: false
    disableMLSD: false
    escapeRegexpMeta: false
    tls: true
    insecureSkipVerify: true
    logTrace: true

However, I can connect to the server using FTPS with LFTP. Here's a working example of a command:

lftp -e "set ssl:verify-certificate no; open ftp://<user>:<pass>@<ip>; mirror --continue  ----scan-all-first --depth-first --only-newer --verbose --no-empty-dirs /source /target;"

What am I doing wrong? Thanks!

Expected behaviour

Connect to server via FTPS.

Actual behaviour

Cannot connect to server: tls: first record does not look like a TLS handshake

Steps to reproduce

1. Set up FTPS in config file
2. Can't connect
