edtFTPnet/PRO has a rich API and provides complex capabilities. There are a wide variety of
FTP, FTPS and SFTP servers in existence, which may or may not implement the relevant
standards.
If difficulties are experienced in connecting to a server or performing operations, a number of
steps can be taken to try to resolve the problem.
1. Ensure that you can connect using FileZilla using the same credentials. If you cannot
connect with FileZilla, it is likely that other clients (such as this one) will also experience
difficulties connecting. Make sure you select the correct protocol.
2. For SFTP, alternatively (or also) use a command-line ssh client to connect to the server
using the authentication method of your choice, and ensure that this works. ssh -vvv can
be used to provide helpful debugging information.
3. If you can connect using FileZilla, try using the appropriate Example Viewer example (with
suitable settings) provided with the distribution.
4. Generate a log file exhibiting the error with the level set to LogLevel.All. This may provide
you (and us) with a clue to the problem.
5. If possible, obtain the server log file to see if it contains any clues to the problem.
6. Search the EDT Forum to see if the problem has been reported and a resolution posted.
The forum is fully searchable and contains advice and answers to many issues that
developers have faced when using this library.
7. Consult the product's revision history to see if your problem has been resolved in a
later version of the software. If your support agreement is current, download the latest
version
(or request it from support@enterprisedt.com), even if your problem is not listed. If you
are unable to resolve the problem and you have a current support agreement, you may
need to contact EDT Support. We will do our best to resolve the problem, including
issuing patches if necessary. Note that Lifetime Subscriptions always have current
support agreements.
When emailing support with a problem, always include a stack trace (if applicable)
and a relevant section of the log file that illustrates the problem. Include as much
information as possible. It will save us emailing you to ask for it.
