worked for me with some minor ajustments (no nist for keyexchange)!

So settings for IPCop (>=2.1.6) are:

Ciphers aes128-cbc,blowfish-cbc,3des-cbc,aes128-ctr,aes192-ctr,aes256-ctr,diffie-hellman-group-exchange-sha256,diffie-hellman-group14-sha1

Ciphers aes128-cbc,blowfish-cbc,3des-cbc,aes128-ctr,aes192-ctr,aes256-ctr tnx

I have a similar problem, but with a new version of synology dsm on a synology nas.

I found this workaround:

But now I get the message "No valid result from SSH Shell" instead of the keyexchange one.
