Why can't I access my server using SSH/FTP?
If you have had multiple login attempts with invalid credentials, it is possible that your IP has been blocked for SSH, SFTP, FTPS and FTP login. We use this mechanism to protect your server against so called brute force attacks.
You can check here whether your IP is blocked for this reason or not:
If your IP address has been blocked, please let us know via our Support, so we can re-enable it.
