| Port | 22 |
Disabling TLS in the Site Manager
This solution works for any FTP user.
- In FileZilla, from the File menu, select Site Manager.
- Click New Site.
- Complete the following fields, and then click Connect:
| Field | What to do… |
|---|---|
| Host | Enter your hosting account’s IP address. |
| Protocol | Select FTP – File Transfer Protocol. |
| Encryption | Select Use plain FTP. |
