Could not negotiate diffie-hellman-group1-sha1 (wodSFTP / wodSFTP.NET / wodSFTPdll)

by DNixon, Monday, July 25, 2016, 17:28 (3041 days ago)

A customer of ours recently upgraded their server and now we are getting a "Could not negotiate diffie-hellman-group1-sha1" error trying to connect using wodSFTP.NET (we are using version 3.4.9.129). We are able to connect using CoreFTP:
SSH-2.0-1.0.0
diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1
client -> aes256
server -> aes256
ssh-rsa
