Hello Friends,
530 Login authentication failed, is a type of response from FileZilla, (FTP Client) when you start connecting to your server by entering proper configuration of server(HOST), username, password and port.
I was also stucked when first time connecting to my Linux based server.
But after some hours spending with error (Critical error: Could not connect to server) that error was solved.
This error comes because of name server propagation to all over world. For this error to be solved you have to check out first,
that where your domain is registered the name servers are properly written in name servers field, then check out,
what is the IP address of your website is perfectly assigned to your domain name "A Records".
then, last thing is, did you waited for approx 24 to 48 hours after changing your name servers on your domain registering website.
When you will check out all these things are correct, then try login again...
and, at this time, when you are logging in check
status : connecting to "Your IP address of webiste": "Port No."
should be there.
IF THESE THINGS ARE CORRECT 530 Login authentication failed, WILL NOT BE THERE, AND LOGGING TO SERVER WILL BE SUCCESSFULL. :)
Rather you have any queries make them commented i will resolve them, as per my knowledge. Thank You for reading this post.
