Command: MLSD
Error: Connection timed out
Error: Failed to retrieve directory listing
Unknown Certificate
Connection timed out. Failed to retrieve directory listing.
Symptom:
After updating to latest version of FileZilla client, all FTP sites stopped working. Getting error unknown certificate, connection timed out, and failed to retrieve directory listing.
Solution:
1. Click on File > Site Manager (or use shortcut key CTRL + S).
2. Click on New Site.
3. Inside new site's General tab, enter your FTP host IP/ domain and FTP port accordingly.
4. In Encryption option, select Only use plain FTP (insecure).
5. For security measure, in Logon Type, select Ask for password (I never trust saving down passwords).
6. In User field, erase out the anonymous username.
7. Hit OK and you're done.
8. To connect to your FTP site, click on Open the Site Manager button (bellow File menu), and select your desired FTP site to connect.
Site Manager Configuration

Note:
I wouldn't recommend saving down login credentials. Be it just username alone or both username and password. In the even of PC being compromised, affected by virus/ malware/ hack, your login credentials still have a chance to survive

FTP transfer is insecure and not encrypted (No security at all). For more secured data transfer, consider using SFTP or FTPS, where data is encrypted.
