What can I check to fix broken FTP connection?

I'm trying to setup remote access for my home PC through ssh, FTP & VNC. Ssh is working, it's time for FTP. My "server" runs under Manjaro with vsftpd as FTP-server. First, I'm trying to access it with FileZilla from Win10 machine, here is connection log:

Status: Connecting to 192.168.50.10:21... Status: Connection established, waiting for welcome message... Status: Insecure server, it does not support FTP over TLS. Status: Logged in Status: Retrieving directory listing... Command: PWD Response: 257 "/home/***" is the current directory Command: TYPE I Response: 200 Switching to Binary mode. Command: PASV Response: 227 Entering Passive Mode (192,168,50,10,127,51). Command: LIST Error: Transfer connection interrupted: ECONNABORTED - Connection aborted Error: Connection closed by server Error: Failed to retrieve directory listing 

I made a port forwarding for FTP in my router and ran test from , here is log:

Command: PASV Reply: 227 Entering Passive Mode (*,*,*,*,43,142). Command: LIST Status: Data connection established. Error: Could not read from socket: Connection reset by peer 

ftptest.net says that this error is due

• A common cause for this problem are broken routers and/or firewalls that interrupt the connection.
• Some broken or badly configured servers can also interrupt the connection prematurely.

I disabled win10 firewall, router firewall, what can I check further?

UPDATE:

I'm trying to login as my Manjaro's user, so I think this user has all permissions to it's home dir. Anyway, I tried to set permissions 777 to home dir - it didn't help. Also I added my user to vsftpd.userlists and added this file to vsftpd.config - still no luck.

I noted in sudo systemctl status vsftpd that

vsftpd[14483]: pam_listfile(vsftpd:auth): Couldn't open /etc/ftpusers

so I created it, and added my user here. Now FileZilla says:

Response: 530 Login incorrect.

, but I'm sure my user and it's password are correct, so I deleted my user from /etc/ftpusers and now I have the same errors as before except missing /etc/ftpusers.

I'm complete newbie in net technologies, so I'm just tried to establish sftp session in Mobaxterm, unsuccessfully:

Connection error: unable to connect to server

UPDATE 2:

I'am still unable to setup FTP, but SFTP works well, so I've accepted the answer.

If you can run ssh then sftp is available. It's just like FTP but with ssh's inbuilt security. The interface looks just the same.
