Hello, for some reason i began receive this error when i try ftp connection.

Status: Connection established, waiting for welcome message...
Response: 220---------- Welcome to Pure-FTPd [privsep] [TLS] ----------
Response: 220-You are user number 2 of 60 allowed.
Response: 220-Local time is now 17:07. Server port: 21.
Response: 220-This is a private system - No anonymous login
Response: 220-IPv6 connections are also welcome on this server.
Response: 220 You will be disconnected after 15 minutes of inactivity.
Command: AUTH TLS
Response: 234 AUTH TLS OK.
Status: Initializing TLS...
Error: Received certificate chain could not be verified. Verification status is 524290.
Status: Connection attempt failed with "ECONNABORTED - Connection aborted".
Error: Could not connect to server
I haven't touched the FTP settings for many months so I think some update may have caused this.
Has anyone gone through this? If yes, how to solve?

Best regards.

Hey there! The first place to check would be WHM >> Manage Service SSL Certificates. Does that show a valid SSL in place for the FTP service?
Hello, thank you for your reply.

The SSL Certificate for all WHM/cPanel services are OK.
The certificate expiration is 4/20/22 so i don't have any another idea...

Best regards.

just fyi

SFTP is essentially FTP over SSH, so it's a completely different protocol than standard FTP. One point to remember is that when you create virtual FTP accounts via cPanel, users can not access SFTP with those authentication details. Only the cPanel account username/password is able to authenticate with SFTP.

are you using FileZilla, if you search google they have a few of these mentions as an error and others just downloaded another ftp software and use that.
