I have a weird issue, I've been using this webserver for months without problems, but this morning I accessed with FTP to move some files, and then every time that I wanted to download or upload files I had this error:
**Filezilla log:** Status: Connecting to IP... Response: fzSftp started Command: open "USER@IP" 22 Error: Server unexpectedly closed network connection Error: Could not connect to server Status: Waiting to retry... Status: Connecting to IP... Response: fzSftp started Command: open "USER@IP" 22 Error: Could not connect to server
and then I tried to use SSH to connect to my webserver and I had this error:
ssh_exchange_identification: Connection closed by remote host
All my other services are up and running in the webserver, the issue is just with SSH and FTP.
what should I do right now?
Thanks in advance!!
