You can try a manual connect with TLS1.2 and manual connect with insecure FTP and see if it works. This error is associated with servers that don't properly support TLS.

> but do you think it's possible to improve this in the library code Sure!

Since you contributed SOCKS4x support into the library you would be the best person to debug this.

If you want to accept all certs just use `ValidateAnyCertificate = True` rather than `AddHandler ftps.ValidateCertificate, AddressOf OnValidateCertificate`.

@svarga91 Please make a new issue and add the detailed FTP logs so we can figure it out.

Can you help debug this?

Can you download the fluent FTP source code, add the project to your solution, run debug mode, put a breakpoint in/near the method that is failing, and step through it...

Can you check now? https://www.nuget.org/packages/FluentFTP/37.1.0

Nice description, but no, never heard of this. Seems like the server is kicking you because you have multiple connections from the same source IP. Maybe try setting a source...

Reopening so the discussion can remain active.
