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

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
Sending password
PWD
Current directory is '/'
Keep alive off...

Could not negotiate diffie-hellman-group1-sha1

Hi.

Can you please update wodSFTP.NET. It is still 3.4.9 but we're currently testing new key exchanges, so currently following are supported:

diffie-hellman-group-exchange-sha256, diffie-hellman-group-exchange-sha1, diffie-hellman-group1-sha1, diffie-hellman-group14-sha1

I believe this will help you out with your server.

Best regards,
Jasmine.
