I am setting up an sftp and I get the following error when I test the connection:
The negotiation of key exchange method has failed
When using WinScp, I have no problem connecting. Does anyone know what the problem could be?
I prefer to use Toad command line shell out and still use WinSCP. You can pass variables to the argument line. It will launch a command line WinSCP which you know will work.
Was this ever resolved?
I am experiencing this issue now. It appears to be related to the algorithms that Toad Data Point may be using that are not supported by our current SSH Server?
Anyway, I am using version 5.7. The algorithms on our SSH Server are: diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha256,diffie-hellman-group15-sha512,diffie-hellman-group16-sha512,diffie-hellman-group17-sha512,diffie-hellman-group18-sha512,rsa2048-sha256,ecdh-sha2-nistp384,curve25519-sha256,curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp521.
Can anyone tell me if my Toad Data point version 5.7 supports these algo's?
This was resolved on version 6.2.3 but then reverted back to its previous behavior on all versions since (including the most recent version 6.4.1.35541 released today). We use sFTP in almost all of our automations. We were stuck on 5.3 for the longest time until I found that it was resolved in 6.2. Please, Quest, this needs to be resolved and a patch made available!
Thanks to everyone for bringing these issues to our attention.
The R&D team is aware of them and is actively working on a resolution.
Updates will be shared as soon as they are available.
Hi again,
Have you had a chance to test this in the latest 2025 R2 build?
I hope you were able to verify that the issue is no longer present.
We have tested this and it seems to be working fine now.
