Unable to log in to linode using FTP or SSH

Log in using ftp, it shows that the connection server is wrong, no response, I do not know what caused it.

The first thing you'll want to check here is that the proper ports are open and accepting connections (FTP uses port 21, and SSH/SFTP uses port 22). You can check your ports with nmap:

nmap -p 21,22 <IP address>

You also might want to check your SSH login credentials. If you're not sure what they are, you can reset your Linode's root password with this guide. From there, you can SSH into your Linode and reset your user(s) password using the instructions from this guide.

Whether or not you're using Filezilla or another FTP client, this Community post has some good tips for troubleshooting FTP/SFTP connection issues:

I can't connect to my host using FileZilla/FTP; Authentication failed, Could not connect to server

Hope this gives you a couple things to try!

Hi @jdutton,

I am having the same issue. Traveling to my girlfriend's parent's house, I am unable to connect via PuTTy, MySQLWorkbench, or Netbeans (FTP). My login configurations haven't changed, they were working fine yesterday using Delta WiFi on my flight, and they even work now if I connect via mobile hotspot.

I tried running your

 nmap -p 21,22 <IP Address> 

with my current IP address in the web GLISH, and I got:

 Starting Nmap 6.47 ( http://nmap.org ) at 2019-10-27 15:42 GMT
 Note: Host seems down. If it is really up, but blocking our ping probes, try -Pn
 Nmap done: 1 IP address (0 hosts up) scanned in 3.04 seconds

Please advise on how to fix. Do I need to whitelist this IP address or something?
