Error 500

What I’ve tried:
– Using FTP to connect, shows the following error ‘Connection attempt failed with ‘ECONNREFUSED – Connection refused by server’.’
– Clearing Cache, but doesn’t work
– Auditing my plugins, but I can’t even access the dashboard
– Increase PHP Limit, can’t access file without FTP and dashboard
– Auditing theme, can’t access without dashboard
– Backup, can’t do it because FTP can’t connect

What I’ve tried when connecting to FTP (Filezilla):
– Entering hostname, making sure it starts with ftp://domain-name.com, credentials for accessing dashboard, port 22 and 21, error: ‘Critical error:
`Could not connect to server’
– Tried using ‘Site Manager > General’

Here are the credentials that I’ve input:
Protocol: HTTPS
Host: domain-name.com
Port: 22
