alfred explicitly binds to the link-local IPv6 address of the interface since version 2016.0. I suspect one of the following caveats might be your problem: * The link-local IPv6 address must match the MAC address of the interface (here bat0) (derived by flipping the 2 bit of the first byte, and adding fe80 and fffe); this ususally breaks when the MAC address is changed after the interface is up * The link-local address must not be tentative when alfred is started (duplicate address detection must have finished; this usually means that the interface must be up for 3 seconds before alfred is started) I hope this helps...
