Error Downloading File With https

David @ Thu Aug 07 16:06:37 EEST 2014
I am not certain if this is too vague of a question but we are having difficulties with clients downloading a certain file type (Autodesk Revit Files). The following is a snapshot of the log:

The person downloading the file ended the process when the download failed. The user has updated java on their computer. Is there any indication from the log what is happening?

Thanks,

David

This issue implies one of two things...

Either a bad client that dropped the connection, or a network issue that interrupted the transfer.

The user doesn't need java on their desktop, has nothing to do with this scenario. Unrelated entirely.

Is this happening continually? What about suing SFTP instead?

Thanks,
Ben

Hi Ben,

Yes, this is an ongoing issue. I had the client download and use Filezilla, and it solved the problem. The only concern with that is having the 20 - 30 people on the project needing to download an ftp client.

But in your first test, they also used a FTP client... What client did they use there?

Why aren't they just using the WebInterface to interact with your server? Then they just use a browser.

Thanks,
Ben

Ben,

I guess I didn't explain myself too well. The problem happens when they are using the WebInterface. To get around the problem I had them use FileZilla.

Thanks,

David

Your log is not from them using the WebInterface. That is a FTP log. They might have used a browser...but it wasn't the WebInterface.

Example:

ftp://domain.com/
http://domain.com/

Both may point to the same place, but the protocol at the front of that URL determines who the browser works with that site. ftp:// means the browser acts as a poor mans ftp client, and a bad client at that. http:// or https:// means the browser loads the rich WebInterface and uses the http protocol for everything...much more reliable.

So check what they were doing as they were not on your WebInterface.

Thanks,
Ben

Ben,

Well, that would explain a lot... this is an older project for this architect so they must be using an older link. Thanks a lot for the insight! We will send out new links which will most likely rectify the problem.

Thanks,

David
