I also tried adding insecure: true to no avail.

It looks like double-bag-ftps doesn't like it when nil is passed in as the auth argument to login.

Can you try adding auth_tls: true to your dandelion.yml. If that works we should probably make it the default.

[chrisdpeters]

I get a different error complaining about the certificate, so that works as expected.

[chrisdpeters]

Your idea sounds like a reasonable default, by the way. I was just trying to get it to work with it set to false.

[scttnlsn]

I think the problem is just that the FTPS adapter is passing nil when auth_tls is false. What's another valid value for the auth argument to login?

[chrisdpeters]

It looks like the more common values are TLS and SSL. TLS-C appears to be another less-common possibility. Probably neither would be helpful in my case.

I should have my boss set up the FTPS again with the bad setup and see what the specific error is for auth_tls: true to see if that's something that Dandelion can work around.

P. S. I tried skimming through the FTPS spec and couldn't quickly find any more info about AUTH.

The Wikipedia article does list some info:
