Failed to open tun socket in namespace

Hi,
Thank you so much for this project!
I'm running a rootless container using pasta. Everything works great but after a
while (anything from minutes to hours) I see the error "Failed to open tun socket in
namespace" in my systemd logs, and my container loses access to the internet.
Do you happen to have any idea how I would go about debugging this?
Thanks a lot in advance :)

PS: I'm running pasta from podman with arguments
--map-gw,--dns,<my-dns>,-i,wlan0,--outbound-if4,wireguard0,--outbound-if6,wireguard0,--config-net
