Difficulty in getting through to my server

SmartFTP advised me recently to update the program, for money. So I paid: why not? It seemed to be a good program.

Ever since it has become a nightmare to transfer files to my server. Before, it always worked, intantaneously, as long as the Internet was working. Slow, when the Internet was slow, but it worked.

Eventually, I seem to get through, and once a connection is established, it seems to stay on. But until then - why, I may have to wait an hour or two. This is not reasonable!

It can't be a password problem, since eventually I get through. My internet is working. Here is the log from a current file transfer:

So, what's up?

Don't blame my server company, the transfers always worked before I "updated" your program. Or my Internet speed - it didn't seem to be a problem before.

[13:39:55] PASS (hidden)
[13:39:55] An existing connection was forcibly closed by the remote host.

Obviously maybe, but this means the connection was closed by the _remote_ host. When it should in fact reply with 230 message if login was OK. Which it doesn't.

1. I suggest you try another FTP client first and if you experience the same problem its highly likely there is something "wrong" with the server.

2. And make sure your username/password is correct.

compare it to a successful login from my log...

[14:34:37] PASS (hidden)
[14:34:37] 230-User domain.xxx has group access to: www

Hello ..

It's a simple problem:
[13:41:25] 530 Sorry, the maximum number of clients (5) for this user are already connected

It basically means you opened too many concurrent connections to the server. To fix it set the number of workers in the transfer queue (bottom window) to 1. Go to menu: Windows->Close All. Then wait 15 minutes and then connect again.

Thank you.

But sorry, that's not it. I have consistently left the number of workers at 1, I understood that much of the transfer queue interface.

My earlier file got through, so it can harldy be a question of passwords. Now I have another file in the transfer queue, it has been sitting there for hours - retrying, and retrying, and retrying, every minute.

-------------------

Ah, but now I reset the kbps per worker to 1, and the file got through. Could this be it? Setting it at 5 shouldn't be beyond the reach of modern technology - if my internet line can't handle it, transfer can always be at a lower rate, can't it?

Hello ..

You open too many connections to the server (e.g. too many remote browser open) or the number of workers are too high in the transfer queue. If you hammer the server with too many connection requests it will ban you after a while as you can see in the log you have posted. So once again. Set the number of workers to 1. Close all Remote Browser windows. Then wait 15-30 minutes or longer. Then connect with 1 Remote Browser. If it doesn't work you are still banned and have to wait longer before you try again.

You can also disable the background connection in the favorite properties in the Transfer dialog. This will save one more connection.
Disable the Background Transfers in the favorite settings Transfer dialog. To access the favorite settings please see: KB: How to edit the favorite settings. https://www.smartftp.com/support/kb/how- ... -f117.html
