Odd Legacy Issue
I've been troubleshooting an odd issue. I have a legacy app... Python 2.5.4 on Windows Server 2008... it can connect to older versions of FileZilla Server but not latest one. It makes the initial connection, but then nothing after- no ability to send/receive files or list directories, etc... connections timeout.. I'm suspecting a port issue, but what would be different between older FileZilla Server and current one for this to happen?
Re: Odd Legacy Issue
What does it say in the log?
Re: Odd Legacy Issue
It might be a good idea to change the log level to get more detail in the FileZilla log:

Re: Odd Legacy Issue
So currently, I see the connection and then nothing after. On the client side, a timeout occurs.

Re: Odd Legacy Issue
Nothing illuminating after additional logging added.
