Let's Encrypt Automatic Upload Certificate via SFTP Setup

[thewolf56]

Hello,

I have been running the Let's Encrypt add-on with Nginx for a little while without a problem for a while.  However, now I need to use the certificates for a couple of other items.

I have setup SFTP and can connect with Putty using Keys, but get an error when I test the connection via the automation for uploading the certificate via SFTP.

I checked the log in the SSH/SFTP server and can see that my OPNsense machine attempts to connect, but I get this error in OPNsense

Host cannot be trusted.
{ "actions": [ "connecting" ], "success": false, "error": "Key mismatch for '192.168.X.XX'; The expected key ({'hash':'SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX1234','key_type':'RSA','key_length':'2048'}) was not found in ([{'hash':'SHA256:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX5678','key_type':'RSA','key_length':'3072'}])", "host_not_trusted": true, "connect_failed": true }

Can anyone tell me what I am doing wrong?  I noticed that there is a key length mismatch along with key not matching, but not sure how to fix on the OPNsense machine.
