Dopus 10 cannot connect to any FTP site

Can anyone please urgently shed some light as to why I cannot connect to any of my FTP sites any more?

I have about a dozen or so connections which all worked perfectly in version 9 this morning. Now I just updated (I won't use the word "upgraded" yet) and can no longer connect.

As an example from one of my connections, if I watch the FTP server's log: I constantly see the following messages (attachment)


Did you try to re-enter one of your FTP sites to see if it works at least that way?

Everything's fine if I connect from FileZilla, DOS FTP, and.... DOpus 9

Firewall or other permissions problems?
I've been using Opus 10 for several months (since the beta days) and I FTP upload/download every day without any connection issues.

I should have been clearer: same PC: Dopus 9, filezilla, etc etc works, Dopus 10 does not.

Yes, I have uninstalled and re-installed. Same problem.

Here's the output when logging on DOpus's side:

Hi there,

Here under Windows7 (HP) and DOpus 10 it works perfectly, below is the log connecting to the gnu ftp:

Opening Connection ftp.gnu.org:21

Maybe it's something of the Trial version only? ...or try to use PASVive mode just in case.

I'm very happy for you :wink:

This is a fully licensed version. And, no, passive mode does not work (but I would not expect it to, with this server)

  • Try toggling Passive (PASV) mode in the site bookmark's Network tab.

  • Make sure your firewall recognises Opus 10 the same as it did Opus 9. It may treat different EXEs or version-numbers differently.

There's your answer. You are trying to make an active connection when you are using a NAT with subnet 10.x.x.x. That's not possible.

You've turned on Active transfers. Change this to use a PASV connection.

Noope:

257 "/" is the current directory
--> CWD /xxxxxxxx/xxxxxxxx/
250 Change directory ok
--> PWD
257 "/MagicLogic/0 Transfer" is the current directory
--> PASV
FD_CLOSE - WSAECONNABORTED: Software caused connection abort
Connection closed
Timeout on Command 1007.

I should re-iterate - I can connect from many other ftp programs, NOT using passive mode. NO firewall is on.

Are any of these public FTP servers that we can try?

fraid not... but I can arrange an account if some kind soul wants to give it a try for me...

Ok, rewinding a bit there... where does that PORT bollocks come from? When I connect using filezilla I get a much more expected result:
PORT 192,168,0,100,202,137

And to answer myself - I suspect it's my VPN. Why is Dopus 10 trying to use my VPN instead of my default internet connection?

And well blow me if it's not all magically ok if I disconnect my VPN. What's D10 doing using that connection?

Can I get a fix easily?

Is your VPN set as the default gateway? Try turning that off and re-connecting to it if so. (Just a wild guess, but it's caused me problems in the past with VPNs.)


I can confirm it is NOT using the default gateway. My properties look identical to yours, leo.

We should also not forget that DOpus 9.x runs on this identical configuration with no problems. I think the inescapable conclusion is that it is a bug in 10.
