Has anyone else dealt with “FTP_INCORRECT_HOST_KEY” when using sftp.createConnection? I have the exact same host key working in my sandbox environment but is failing in production. This is occurring within my scripts as well as the SFTP Connector SuiteApp.
b
your sftp server probably has different keys
choose a different one to use
s
How would I find that out? Running 
ssh-keyscan
always gives the same host key and this EXACT key works in SB but not production
I generated a new SSH key and tried that out just to be safe, but had the same problems (and host key shouldn’t change anyway). It’s happening with two different SFTP servers too: works in SB, doesn’t work in prod
b
use -t to specify types of keys
s
Yeah, sorry I should have mentioned the whole command, but I did specify the key type (rsa). Same situation 😞
b
there are 3 options for that argument
try all of them
s
Yeah, if you don’t define a 
-t
you get all of them. Servers only have rsa
ed25519
and 
dsa
give nothing
b
ed25519
is not 1 of the 3 options
s
rsa1
my bad, it’s late. Anyways 
-4
and 
-6
(forcing ipv4 and ipv6) give the same host key. Including 
-p 22
to specify the port gives the same. I’m confident the host key is correct because it’s working perfectly in my sandboxes (tried both sandboxes we have), but as soon as I try in production it fails
b
if your server only has one host key, something weird is happening because there is only one correct value
s
Yeah, it’s gotta be a NetSuite thing. I’ve opened a case so fingers crossed they can find something
b
if there are multiple host keys, you should be trying those instead, because production and sandbox may be ignoring different keys
n
If you have saved the Host key in a custom record/custom field, make sure it is not Free-Form Text but Text Area. Also compare the field with your sandbox. Free-Form Text field tends to remove the extra character to limit the string.
This has happened to me.

Thing is, I’m getting the exact same behavior using the SFTP Connector SuiteApp. I installed it in both production and sandbox -> Entered all the same values and uploaded the same key file (Setup->Company->Keys)… I even ensured the id was the same 
custkey_sftp_key
-> SB1: Pass, SB2: Pass, Production: “FTP_INCORRECT_HOST_KEY”: “”Provided host key does not match remote server’s fingerprint.”
