SMM Can't Connect to Dedicated Server via SFTP

Hi all... I have a dedicated server running in AMP. I can connect to the sftp using an FTP client from my desktop PC no problems. However SMM (v3.03) is not connecting properly. I can add the server using Simple Mode however if I try to do anything like install or enable mods etc I get the "Something went wrong" "failed to remove old mods: failed to delete mod directory: failed to delete path: file does not exist" error. I generated the Debug and I can see the following line: "WARN","msg":"failed to get remote server metadata","error":"failed to get game version: failed to validate installation: failed to connect to ssh server: dial tcp [ip:port]: connectex: No connection could be made because the target machine actively refused it.","path":"sftp://user:pass@**/"} I have changed my password so there are no special characters and as I said I can connect to the dedicated server fine with a desktop client. I've spent a few hours trying to work through this by I can't figure out why SMM won't connect. Debug attached.
Solution:
I seem to have fixed this myself. I deleted all mod folders from server (and steam client on my desktop). I removed the server details from SMM and all mods from SMM. I then started the whole process from scratch and it worked. So there must have been something strange that was stopping it from working that starting over seems to have resolved.

You should shut down the dedicated server executable before trying to install mods on it.

Some additional info that I have discovered... I can see in the logs that I successfully login when attaching to the server with SSM. I did have a password with a special character. I have changed that but I still get the Something when wrong error. It looks like the plugins are getting installed but there are no files being installed in the Binaries folder. For example SML/Binaries/Linux is empty. I have attached another Debug after my password change.

Does your SFTP account have permissions to write and delete files? This definitely seems odd
