Users can fetch my shares list but can't download from my new slskd instance

[Atronach]

Hi team,

I used to run an slskd instance from an RPI in my home with no issue whatsoever.

I've just spun up a new instance of slskd in an LXC running on Proxmox a few days ago.
From this instance, I can fetch files from other users and they can query my shares, but they can't seem to establish a direct TCP connection with that instance to download my files, I get timeouts reports in my logs at every attempt.

Is there something I might be missing here ?
I'll be glad to discuss the details of my setup further in private.

Cheers and thanks for the amazing work over the years !
