Rebex SFTP Trial Version

Question

Hi,

I’ve downloaded the trial version, works like a charm in the development environment, but when I copy the website to a server so that management can see the app, the Rebex component won’t work.

Windows Event Viewer has the following errors… I’ve added a reference to the assembilies in web.config, but I still continue getting the same message… Is there anyone that can think of why the components would keep giving this message in windows event viewer?

Answer 1

This looks like the following events occured:

1. An SftpException was thrown by one of Sftp object's method.
2. During the processing of this SftpException, another error occured because of some serialization issue. It looks like the SftpException was passed to a different application domain, although I don't know why that might happen.

Would it be possible to use Sftp object's LogWriter property to create a communication and error log at the server and mail it to us for analysis? That should make it possible to tell what is going on.

Answer 2

Looks like the SFTP error was that the website was unable to connect to the FTP server... apparently port 22 was blocked outbound on the production server... Here's the stack trace of nested exceptions...
