Hello community,
I am having a lot of errors with my Apple TV 4K connecting to a LAN ftp server:

When this happens, I am seeing freezes and artifacts (while audio keeps on), very similar to what is described in this topic
The ftp server is a XigmaNAS/FreeBSD/ProFTPD. It works perfectly with all other ftp clients I have tested, but obviously it is not easy to mimic the way infuse connects to the server.
It could be an issue with the ProFTPD server, as google search about “error uncorking socket fd 15” shows EPSV as a possible reason, but to find a solution I need to understand how firecore attempts to connect (if indeed trying EPSV mode).
I opened a support ticket, hoping that someone from firecore would clarify this for me, but unfortunately I am getting canned responses.
Any ideas?
